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 ...

At points I might do something that might be dangerous because I'm comfortable with some tools or techniques but please always use your common sense and don't try everything you see here.

Electromechanical relays will require a transistor driver circuit in order to be driven by the Arduino. The typical circuit for driving a relay is the same as the transitor driver above with the ...

“Arduino Self-Timer” project presented here is a low ... just use this output to drive the electro-magnetic relay with the help of a suitable transistor-based relay driver circuit. Note that the timer ...

Using a transistor Instead I came up with my ... is there a better way to convert the RC receiver output to something the Arduino can use? Relays require power, so it would be nice if there ...

To interface with the Arduino Uno, you’ll need a custom shield that houses essential components such as relays, transistors, power supplies, and an operational amplifier. These components work ...

Fig. 1: Add this relay to prevent shorted transistors in the MW-1. Usually after a transmitter is discontinued, any hope of upgrades or improvements fades. Some enterprising engineers can’t help but ...
