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 ...

IN - This pin is also called the control pin because it is used to control the output of the relay. COM - is connected to the device you intend to connect. NC - terminal is connected to the COM ...

If you are interested in building robots, then it is certain that you need to learn how to control the speed and direction of a DC motor, and in one of our previous tutorials, we did just that using ...

Microcontrollers like Arduino are designed to control small loads, such as LEDs or sensors, directly from their output pins. However, these pins can only supply a limited amount of current (typically ...
