DIY Home Security - New Video: youtu.be/UBNpL5WpJ54
In this tutorial we will learn how to make an Arduino Security Panel System with using Keypad and LCD Display.We will be able to open the door by entering the correct password.
Required Hardware:
Arduino Board:
goo.gl/UyGYeF
amzn.to/2LZr6t4
Keypad 4x4 :
goo.gl/jtGlx5
amzn.to/31xaRYE
LCD 16x02:
goo.gl/8S27hc
amzn.to/3bbBgzu
Breadboard:
goo.gl/yCa8hX
amzn.to/3qxLxwm
Potentiometer 10k:
goo.gl/c90Uix
amzn.to/3dlgYq1
Resistor 220 Ohm:
amzn.to/3jXMJXs
LED:
amzn.to/3qxSs8O
Jumper Wires:
amzn.to/3doetmT
Recommended Items:
Use Your Muscles in Project - amzn.to/3wdL45C
37 Sensor & Module Packages - amzn.to/3m66WeQ
Try this Robot Arm - amzn.to/3fq8DCl
Best Resin 3D Printer - amzn.to/39tY8KB
Arduino Compatible Kits - bit.ly/2J2AFF7
Banggood Spring Sale - bit.ly/3slMbOn
LCD 16x02 Connection:
The Arduino's +5V and GND will be connected to the pin of the breadboard
The LCD has 16 pins and the first one from left to right is the Ground (GND) pin
The second pin is the VCC which we connect the +5V pin on the breadboard.
Next is the Vo pin on which we can attach a potentiometer for the contrast of the display
The RS pin will be connected to the A0 pin of the Arduino.
The RW pin will be connected to the GND pin of the breadboard.
The E pin will be connected to the A1 pin of the Arduino.
Keypad 4x4 Connections:
The keypad has 8 pins, 4 of them are for the rows and other 4 pin for the columns.
The keypad I'm using is 4x4. It has an additional connection input. The keypad used in the circuit diagram is 3x4.
The Keypad's pins will be connected respectively to the Digital 1-2-3-4-5-6-7-8 pin of the Arduino.
