LED lights are becoming more and more popular because of their energy efficiency, durability, and brightness. However, sometimes you may want to dim the lights to create a cozy atmosphere or reduce the brightness to save energy. This is where a light dimmer circuit comes in handy.
In this tutorial, we will use an Arduino board, a MOSFET, a few resistors, capacitors, and an LED to create the circuit. The Arduino board will act as the controller, sending signals to the MOSFET to adjust the brightness of the LED light.
We will start with an introduction to the components we will use in the circuit, including the Arduino board, the MOSFET, and the resistors and capacitors. We will also explain how the circuit works, and the principles of pulse-width modulation (PWM), which is the technique we will use to control the brightness of the LED.
Next, we will show you how to set up the circuit on a breadboard, step-by-step, and how to connect the components to the Arduino board. We will also explain how to write the code for the Arduino board to control the circuit and adjust the brightness of the LED.
We will then test the circuit and show you how to use the Serial Monitor in the Arduino IDE to monitor the output of the circuit and adjust the brightness of the LED. We will also demonstrate how to use a potentiometer to adjust the brightness of the LED.
Finally, we will show you how to assemble the circuit on a PCB (Printed Circuit Board), which is a more permanent and professional way of building the circuit. We will explain how to design the PCB layout, transfer the circuit diagram to the PCB, and solder the components onto the PCB.
By the end of this tutorial, you will have a clear understanding of how to create a light dimmer circuit for LED lights using Arduino, and the skills to build your own circuit from scratch. Whether you are a beginner or an experienced electronics enthusiast, this tutorial will provide you with valuable insights into the world of electronics and Arduino programming.
So, sit back, relax, and join us on this exciting journey of building a light dimmer circuit for LED lights using Arduino!

![How to Run AI model Raspberry Pi? STEP BY STEP Ollama Raspberry Pi LLM Setup
Can you really run a Large Language Model (LLM) on a Raspberry Pi? In this video, I’m pushing the limits of this tiny SBC to see if local AI is actually practical and if we could setup Ollama Raspberry Pi. I’m sharing my full hands-on experience—the crashes, the overheating, and the fixes that finally made it work.
I’ll walk you through the complete installation of Ollama and Open WebUI using Docker, and why I chose TinyLlama as the go-to model for the Pi 4 and Pi 5. We’ll also tackle the 3 biggest roadblocks I faced:
Storage limits (Dont make my 16GB mistake!)
Memory crashes (Fixing Signal: Killed with Swap)
Thermal throttling (Why cooling is mandatory)
This video provides step-by-step instructions to run an artificial intelligence model directly on a Raspberry Pi. Well cover setting up the necessary OS and configuring the system to execute commands for models like tinyllama using Ollama, which enables local AI. This guide will help you get a local LLM up and running, showcasing how to use Open WebUI for a complete setup.
