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 ...

While there are a couple of open-source brushless drivers already available, [neuromancer2701] created his own brushless motor controller on an Arduino shield. [neuromancer2701]’s shield is a ...

ClearCore CLCR-4-13 is an industrial IO and motion controller that can be programmed using the Arduino IDE. It handles up to four axes of step-and-direction motion control (500kHz max step rate), and ...

[JonBush] recently did a beautiful build of an Arduino-based fireworks controller ... Driving the firing relays on both sides makes it harder for a stuck output to fire accidentally.

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 ...

grbl is stepper motor controller firmware for three-axis cnc machines ... that are too powerful for the normal drivers included on grbl Arduino shields (or integrated Arduino+drivers equivalents), and ...
