This project demonstrates how to interface a relay module with an Arduino to control high-voltage appliances safely. The setup involves using a relay as a switch, allowing the Arduino to control ...

The relay module will need 5V from Arduino to power up and will get input from four different digital pins of the Arduino. Now let’s connect the relay module to your home appliance. Take the positive ...
