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 is driven using an NPN transistor (BC547), which allows a small control signal to safely switch a relay. This makes it possible to control electrical devices such as lamps, motors, or ...
