I had a few problems with the PWM part mainly because the fan made a disturbing noise so I had to add a simple RC filter at the output of the PWM pin on the Arduino board. I used an LCD shield to ...

Fortunately, with a bit of electronics hacking, you can get those fan blades whirring without having to flip a switch. It’s a fairly simple project, too: just hook an Arduino Uno up to a motion ...

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 ...

This is an easy tutorial showing how you can control the brightness of an LED or adjust the speed of a DC fan using Arduino Board, a small BC547 transistor and a potentiometer. In my example the whole ...

powering the motors of an RC car); for those cases, 1sheeld is hoping community input will tell them what functionality their base board needs. With that said, like any good Arduino shield ...

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 ...

A teacher I know is stuck, with only npn transistors in the supply cupboard and the need to create a reversible motor drive for an Arduino project. Reversing ‘bridges’ have four switches (relay ...
