Automating home appliances and lighting using relays, sensors, and microcontrollers is a practical and fun DIY project that can enhance your home’s convenience and efficiency. Below, I’ll outline the steps to create a basic home automation system using an Arduino, PIR motion sensor, and relay modules to control lights and appliances:
Components you’ll need:
Arduino board (e.g., Arduino Uno) PIR motion sensor Relay modules (1 or more, depending on the number of devices you want to control) Home appliances or lights (ensure they can be controlled via relays) Breadboard and jumper wires Power supply for Arduino (e.g., a USB cable and adapter) Circuit Connections:
