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 ...

What’s a hybrid relay? How does it work? What are its key building blocks? Whether you are designing a power control system or tinkering with a do-it-yourself automation project, it’s important to ...
