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 ...

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 ...

The compressor is made up of a used BMW air suspension compressor (manufacturer is WABCO, the same part is also used be Mercedes), some empty 0.95l oxygen tanks (those used for small oxy-acetylene ...

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 ...

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 ...
