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 ...

The article is a tutorial on how to control 16 relay through Arduino microcontroller with Ethernet shield W5100. Hello, I'm going to share again with another project that helps many of you to solve ...

The Relay is a useful tool to magnify your Arduino’s control ability! Feed the control signal through the Grove interface and the relay open or close the external circuit that is connected to the ...

In this project, we are going to build something very simple project, a temperature controlled relay that is used to turn on a dc fan. You can actually change the DC Fan to other electrical devices ...

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 ...
