Introduction: In the pursuit of efficiency, automation has become a key player in simplifying daily tasks. One such innovation is the utilization of motion sensors coupled with Arduino technology to ...

In this quick Arduino tutorial I will explain how you can control a relay using the Arduino Board, one 1K and one 10K resistors, 1 BC547 transistor, one 6V or 12V relay, one 1N4007 diode and a 12V fan ...

A relay is a device used to respond to an input signal and provide a connection between two or more devices. It can be used to control AC-powered devices, such as lights, fans, or other household ...

You can create a release to package software, along with release notes and links to binary files, for other people to use. Learn more about releases in our docs.

Built an IoT-based home automation project using an ultrasonic sensor, 2-channel relay module, 16x2 LCD display, and Arduino UNO board to control a bulb automatically. The system turns the bulb ON ...

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 ...
