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 ...

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 ...

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 ...

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 ...

So it's welcome to see a basic introductory tutorial on using the wireless protocol on the Arduino website. With consumers in mind, Matter is designed to enable a range of brands to connect around 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 ...
