Momentary Button with Addressable LED

HackMakeMod 2024-10-05 | Check out our Forum post: forum.hackmakemod.com/index.php?threads/momentary-push-button-with-ws2812-led.29

Product Link (NOT SPONSORED): https://a.co/d/h88Oyrl

This push button from ChromaTek, purchased on Amazon, is different from standard momentary buttons because it has an addressable RGB LED built in (using a WS2812 LED). That means, with a microcontroller (like an Arduino) and some programming, you can control the color, brightness, and effects like blinking or fading.

Specifications:
Type: Push Button (Momentary)
Current Rating: 5 Amps
Operating Voltage: 5V DC
Connector Type: Clamp (with included wire harness)
Mounting: 19mm Panel Mount
Material: Stainless Steel (IP65, water-resistant)
How It Works:
When you press the button, the "momentary" action connects the Normally Open (NO) terminal to Common (COM). This sends a signal to the microcontroller that the button is pressed. Releasing the button breaks the connection, switching it back to Normally Closed (NC).

Addressable RGB LED:
The LED inside the button can display any color, thanks to the WS2812 RGB LED. It needs a PWM signal from a digital pin on the microcontroller. You can control the color and brightness by sending the right data. For reliable operation, especially with longer wires, it's recommended to use a 220-470Ω resistor on the Data In line to protect the signal.

If you’re using multiple buttons, the Data Out pin lets you chain them together in series without needing extra connections.

Wiring Breakdown:
Here’s how to wire the button:

Normally Open (NO): Connect to a digital input pin on your microcontroller.
Common (COM): Connect to ground.
Power In (3.3V-5V): Powers the LED, no need for an external resistor.
Data In: Connect to a digital output pin on the microcontroller for controlling the LED.
Data Out: Use this to connect to the Data In of the next button if you want to chain multiple buttons together.

Use Cases:
Status Indicator - In one setup, I used the button to change colors based on system status, synced with an OLED screen.
Servo Control - In another project, I connected the button to a servo-driven needle gauge, cycling through different colors for different positions.

Summary:
This button is practical for projects that need feedback, like custom control panels or visual indicators. It’s easy to wire, especially with the built-in resistor for the LED, and the IP65 rating means it’s protected against dust and water.

I’ll have the code and more details available on our forum if you want to try it out for yourself... forum.hackmakemod.com/index.php?threads/momentary-push-button-with-ws2812-led.29

Capacitive Buttons

HackMakeMod 2024-09-06 | Capacitive Touch Buttons

Did you know you can create capacitive touch buttons with just a resistor, some metal, and an Arduino? You can even activate them through materials like thin plastic or paper, making it ideal for sleek, hidden interfaces.

Here’s how it works: Using the CapacitiveSensor.h library with an Arduino, a pulse pin sends a 5V signal through a 10 mega-ohm resistor to a metal plate, which acts as the touch sensor. In less than a second, the voltage at the plate climbs high enough for the sense pin to detect any change. When you touch the plate, your body adds capacitance, and that slight increase causes the voltage to rise more slowly. The Arduino detects this delay, interpreting it as a touch.

In my project, the touch plate toggles an LED on and off with each touch. It's a simple but effective system that adds interactivity to any project.

A Real-World Example
I took this concept further by creating three capacitive touch buttons. Instead of using metal plates, I formed copper rings from household wiring to act as sensors. Then, I placed these rings behind a thin plastic surface with a strip of addressable LEDs. The buttons light up when touched, creating a responsive visual element.

But, there was a catch! I noticed that the wires themselves could sense touch, even through their silicone insulation. Not ideal.

Fixing False Triggers
To solve this, I switched to shielded wire from an old audio cable. I connected the copper rings to the center wire and grounded the shielding. This setup stopped the wires from responding to touch while keeping the buttons perfectly functional. The result? A reliable, professional-looking touch interface that only triggers when and where it’s supposed to.

If you’re experimenting with capacitive touch sensors, remember that wire shielding can save you a lot of headaches!

Time of Flight Sensor

HackMakeMod 2024-08-22 | A Time-of-Flight distance sensor can measure distances up to two meters with millimeter accuracy.

It works by emitting an invisible laser pulse and timing how long it takes it to reflect back from an object.

Ultrasonic sensors work similarly using sound waves, but they’re less accurate because different surface materials can absorb or scatter the sound waves.

Additionally, you can use the XSHUT pin to conserve power by turning the sensor off when it’s not needed. And the GPIO1 pin can be programmed to trigger an interrupt under certain conditions, reducing the need to constantly poll the sensor in your code.

Time-of-Flight sensors cost more than most hobby sensors, but their $3-$4 price tag is well worth it for the added precision.

Digital Hall Effect Sensor

HackMakeMod 2024-08-17 | The A3144 is a Unipolar Digital Hall Effect Sensor with three connections:
VCC (4.5-24V)
GND
OUTPUT (open-collector, requiring a pull-up resistor)

This sensor is typically in an 'off' state but switches 'on' when it detects the presence of a magnetic field from a specific polarity. Think of it as a switch that activates based on the proximity of a magnet. Specifically, it responds to the south side of a magnet when it’s close enough to the front of the sensor. However, if the north side of the magnet is applied to the back of the sensor, it can also activate.

The A3144 includes built-in hysteresis, ensuring stable activation and deactivation, which prevents false triggering due to minor magnetic fluctuations.

Digital Hall Effect Sensors like the A3144 are invaluable in applications requiring zero-friction detection. Common uses include detecting the trigger points on a rotating wheel to count rotations or measure speed, as well as in tachometers, brushless DC motor commutation, and proximity sensing.

For Loop - Hardware Only

HackMakeMod 2024-03-16 | In programming, a 'for loop' executes operations a predetermined number of times.… Like blinking an LED five times when I press this button.

Do you think we can build this with just hardware and no software?

Of course!
We just need the help of some classic transistors and integrated circuits.

First we need an SR Latch built from two transistors. This holds a binary state and changes it based on input signals. This will turn the sequence on, when the button is pressed, and then off after the set number of cycles complete.

Next we need a 555 timer to work as an oscillator creating the pulses.

We can set the timing based on the resistors and capacitor we use.

Finally we’ll feed these pulses into a decade counter. This integrated circuit advances by one count with each pulse. We’ll add a wire to the 5th count output, sending the signal back to the SR Latch, and stopping the sequence.

Simultaneously the same output will be sent to the reset pin on the decade counter.

So now, when I push the button the LED blinks five times and then stops automatically.

Both the 555 Timer and the 4017 Decade counter were introduced over 50 years ago! And they are still being used today!

#FlexibleFilamentLED

HackMakeMod 2024-02-29 | The Flexible Filament LED

This style has been available for years in consumer bulbs. But recently these 3V versions have become available. Unfortunately datasheets seem non-existent leaving us in the dark!

I noticed they seem to run 100 LEDs in parallel. On lengths over 120mm they run another parallel section in series to make up the remaining length.

If I underpower the filament I can see the individual LEDs and it ruins the effect. They need to be brighter to look more like a solid tungsten filament. But overpowering them is bad.

Most sources recommend limiting the current to 50 or 100mA.

But I did some testing and let one run for 3 days at 200mA - it seemed to be just fine. However the 250 mW resistor was understandably hot since it was burning off the excess 400 mW!

At 5V I recommend using a 22 ohm resistor for any length up to 120mm. However, longer versions need more current, so I recommend two 22 ohm resistors in parallel. This reduces the resistance and doubles the current capacity, keeping your resistors cool.

I’m thrilled to have some new components in my toolkit!

I feel like these new filament style LEDs are gonna unlock a lot of creative options for future projects!

#breadboard

HackMakeMod 2024-02-20 | How to use a breadboard

Understanding how to use a breadboard is foundational. It's the canvas for your electronic creations, a place where components meet and circuits come to life. But before you start plugging in wires and components, let's break down how a breadboard works and why it's set up the way it is.

The power rails - These run along the length of the breadboard on both outer sides. They’re meant for distributing power across your circuit. Despite marked the same on both sides, these rails aren't connected, which is intentional. This design allows you to use different voltage levels on the same board, although most projects typically require just one power source. To bridge this gap, simply use jumper wires to connect the power across the breadboard as needed.

Terminal strips - These are connected vertically, in sets of five holes across on each side, but here's the catch – there's a split right down the middle. This split makes it possible to use integrated circuits (ICs). Without this division, placing an IC across the middle would connect all its pins together – obviously not what want!

If you're new to this, remember that your first build doesn’t have to be a masterpiece. In fact, striving for a flawless design straight away can be overwhelming. Your main goal is to make the circuit work. Aesthetic and efficiency come with time and practice.

Speaking of practice, don't shy away from rebuilding your circuit. It might seem tedious, but repetition is a powerful learning tool. Each time you reconstruct your project, you'll notice new ways to streamline and tidy up your design. Personally, I find myself rebuilding circuits up to five times, not for the sake of perfection, but for understanding and improvement. It's all about getting comfortable with the components and the breadboard layout.

Understanding and using a breadboard effectively is a critical skill in electronics. It's a step towards bringing your ideas to life. Start simple, be patient with your learning curve, and don't be afraid to dismantle and rebuild. Each iteration is a step closer to not just a cleaner build, but a deeper understanding of how electronic circuits function. Remember, every expert was once a beginner.

HackMakeMod 2024-02-07 | The Nano V3 designed by Arduino was originally released in 2008 and it’s still going strong today!
That’s because it has broad support and more than enough speed and memory for most DIY projects.
ATmega328 Microcontroller with an 8-bit processor clocked at 16 MHz
32 KB of flash memory
2 KB of SRAM
1 KB of EEPROM

The Nano’s small footprint and 20 digital I/O pins makes it perfectly suited for breadboards and prototyping.
6 PWM outputs
8 Analog inputs
Digital outputs operate at 5V (HIGH)

It supports a broad input power range of 7 to 15 volts, yet I often power it with a single-cell lithium battery, connected to the 5V pin, and it performs really well!
Lithium Polymer 3.7-4.2V

One of the biggest drawbacks to the Nano has been the Mini USB port. This style hasn’t been useful since the 2000s. But recently Nano V3’s with USB-C connectors are entering the market at around $6! This makes it possible to get multiple units and not feel bad if you’re permanently soldering one into a project.

#thermistor

HackMakeMod 2024-02-02 | Project Code Here:
ccbsp6qd6kmk4zon-49927520424.shopifypreview.com/blogs/projects/thermistor-digital-thermometer

A thermistor is a special type of resistor whose resistance changes significantly with the temperature.
Operating Temperature Range:
-67 to 490F (-55C - 250C)

Here we have two regular 10K resistors in series, configured as a voltage divider. This is a way to use resistors to set a specific voltage.

If we start with 5V and measure in between the two 10K resistors we get 2.5V, half of the source voltage.
Show formula

At 77 degrees Fahrenheit, a 10K thermistor will measure at 10,000 ohms. Now if we replace one of those 10K resistors with a 10K thermistor, we will get a variable voltage depending on the temperature.

If we connect this junction to a microcontroller’s analog input we can read this voltage and run a formula to convert that reading into a temperature… then we send that reading to a display.

I added a button and additional code to switch between Celsius and Fahrenheit.

I’m curious to see if my code works for triple digits…
(Use a torch to heat it)

How about negative numbers…
(spray it with canned air)

Because of the tolerance in the various components, we can’t expect this to be 100% accurate straight away. So I’m going to replace the other 10K resistor with a potentiometer so we can have a way to calibrate it.

A thermistor is another highly valuable sensor you can add to your DIY toolkit. You can buy a pack of 50 for like $7 on Amazon!

This project is more than a practical tool, it’s an excellent introduction to the world of electronics and Arduino.

Choosing a Resistor for your LED

HackMakeMod 2024-01-10 | hackmakemod.com/blogs/projects/choosing-an-led-resistor

Working with LEDs is both fundamental and intriguing. However, the key to using LEDs effectively lies in understanding how to select the right resistor. This not only ensures you don’t murder your LEDs but also prolongs their life.
Body:

LEDs are characterized by two critical parameters: forward voltage and current. The forward voltage, typically ranges from 2V to 3.2V depending on the color and size of your LED. This is the voltage required to light up the LED. The current, often around 20mA, is what the LED needs to operate efficiently without being damaged. Even though many LEDs can handle a burst up to 100mA, it’s better to stay under 20mA.

Applying Ohm's Law:
Ohm's law states that the voltage across a conductor is directly proportional to the current flowing through it.
The formula (R = V/I) is your best tool for calculating the necessary resistor value. Start by determining the voltage drop across the resistor, which is the difference between your power source (like a 9V battery) and the LED's forward voltage. For instance, using a red LED with a 2V forward voltage in a circuit with a 9V battery results in a 7V drop across the resistor.

Choosing the Resistor:
Once you know the voltage drop, divide it by the LED's current requirement to find the resistor value. Continuing our example, a 7V drop for a 20mA LED gives a resistor value of 350 ohms. If you don't have the exact value, opt for a higher one to ensure safety, like a 1K ohm resistor.

Picking the right resistor for your LED isn’t just about making it light up; it’s about precision and longevity. Now you are well on your way to creating efficient and durable LED circuits.

Unlocking USB-C Power 5v 12v 20v

HackMakeMod 2024-01-07 | hackmakemod.com/blogs/projects/usb-c-pd-power-trigger-module

USB-C chargers can do more than you realize. Most can output 5V, 9V or even 12V… and some higher power models can even do 15 and 20V!
Straight out of the plug we’ll only get 5 volts by default. But if we use one of these Power Trigger Modules to communicate with the charger we can set it to a different voltage by soldering these jumper pads.
USB C chargers actively communicate with the device they’re connected to in order to set the voltage and current limits.
Why am I excited about this? I was able to buy a 5 pack for 12 bucks! I added some stiff wire, 3D printed some little enclosures and now I can have various voltage breadboard projects and use just one power supply.

HackMakeMod 2024-01-06 | Get the files here:
hackmakemod.com/blogs/projects/dewalt-bit-holder

If you're like me, constantly switching between different screw bits in your DeWalt drill, you've probably encountered the challenge of keeping them organized. DeWalt includes a metal belt hanger in their drill packages, but it can be more of a hindrance than a help. However, there's a solution - crafting a custom bit holder that's not only practical but visually blends with the drill.

Integration: The bit holder should seamlessly merge with the drill's appearance, giving it a factory-fitted look.
Ease of Fabrication: The design should be simple enough for anyone to replicate, utilizing 3D printing with readily available materials.
Functionality: The holder must securely accommodate multiple standard-sized screw bits, making them easily accessible during your work.
Starting Point: Begin by identifying the attachment point on the drill where the holder will connect. Ensure it snugly fits the drill's mount.
Bit Compatibility: Consider the standard size of screw bits and design the holder to accommodate them comfortably.
Printability: Strive to create a 3D model that can be printed without supports by standing it on one end.

Capacitors can Explode?! 🤯

HackMakeMod 2023-12-18 | Two types of failure in electrolytic capacitors...

1. Venting:
Electrolytic capacitors are designed with safety vents on the top or bottom - these are scored lines or rubber bungs that allow the capacitor to relieve pressure. Venting occurs when the internal pressure within the capacitor builds up, typically due to overheating, reverse polarity or overvoltage conditions. This can cause the electrolyte to boil and produce gas, increasing the internal pressure. The vent is a safety feature that allows this pressure to be released in a controlled manner, preventing the capacitor from exploding. When a capacitor vents, it may emit electrolyte, which is a messy failure, but it's a preferable alternative to an explosion.

2. Explosion:
If an electrolytic capacitor is subjected to excessive power, such as extreme overvoltage or reverse polarity, it can explode violently even if it has proper venting, due to the rapid buildup of pressure that the vents cannot relieve quickly enough. This is a catastrophic failure where the capacitor casing ruptures violently, potentially ejecting pieces of the casing and spewing out electrolyte. This can damage other components in the vicinity and is a serious safety hazard.

In both cases, the capacitor will no longer function as intended, and the circuit it was a part of will likely fail. To minimize the risk of such failures, it's important to ensure that capacitors are not subjected to conditions that exceed their rated tolerances and that they are installed correctly. Regular inspection and timely replacement can also help prevent such failures, especially in applications where capacitors are subjected to harsh conditions or continuous operation.

How do Light Dimmers actually work? #electronics #technology

HackMakeMod 2023-12-14 | TRIAC dimmers operate based on the principle of phase-cut dimming, which involves altering parts of the AC power waveform to control the brightness of lights, typically incandescent bulbs. These dimmers use a TRIAC (Triode for Alternating Current) semiconductor device to chop either the leading or trailing edge of the AC waveform. The leading-edge dimming is more common with traditional resistive loads like incandescent bulbs, while trailing-edge dimming is designed for capacitive loads such as LEDs. By adjusting the portion of the waveform that is delivered to the light, the TRIAC dimmer effectively reduces the total energy supplied, resulting in dimming.
However, TRIAC dimmers were originally designed for incandescent bulbs and can encounter compatibility issues with LED lights. Since LEDs have different electrical characteristics, using a TRIAC dimmer with them can lead to problems like flickering, buzzing, or an incomplete dimming range. This mismatch arises because TRIAC dimmers are not optimized for the low power and electronic nature of LED lighting, making them less suitable for modern LED applications.

LED dimmers are specifically engineered to control the brightness of LED lights, which require a different approach compared to incandescent bulbs. The most common method used in LED dimming is Pulse-Width Modulation (PWM), where the power is rapidly switched on and off at a high frequency. The perceived brightness is controlled by adjusting the duty cycle, which is the ratio of the "on" time to the "off" time. Another method, less common in residential settings, is Constant Current Reduction (CCR), which directly regulates the current supplied to the LEDs, ensuring a constant light output.

Don't miss out on our hands-on tests and findings that could revolutionize your approach to home lighting. Watch now for an illuminating journey through the world of dimmers!

For Your Reference:

PWM (Pulse-Width Modulation) dimmers work by rapidly switching the LED on and off at a frequency that is typically not perceptible to the human eye. The perceived brightness is controlled by varying the ratio of the "on" time to the "off" time (duty cycle). This method does not actually change the voltage or current but controls brightness by varying the amount of time the LED is turned on.
