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 ...
Q: From the electronic hardware perspective, I've run across a situation lately that concerns me. It involves the ‘rx' switch and whether the lock relay gets activated when an RX signal comes in to an ...
