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 ...

Testing relays and their circuits in vehicles doesn’t always require a trip to the bench. With a few simple tools and ...

Wondering how exactly you would wire an electric fan with a relay on your classic car or hot rod? Well, you came to the right place.

For one, the sound doesn’t directly control the solid state relay used in the fan controller. When the microphone equipped Arduino detects enough noise, it will start a timer that keeps the fan ...
