I made this project because I wanted a way to automatically control the speed of a DC fan according to the temperature read by a LM35 sensor. I had a few problems with the PWM part mainly because the ...

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.

Now the speed can be controlled with a pot. Once control of the fan was sorted, [tinyboatproductions] decide to add an OLED display to show the fan speed and power condition, which is a nice touch.

You can salvage some nice motors out of optical drives but they can be tricky to control. That’s because brushless DC motors require carefully timed signals used in a process called Electronic Speed ...

Must admit I'm not up to speed with Matter, a way to standardise IoT elements. So it's welcome to see a basic introductory tutorial on using the wireless protocol on the Arduino website. With ...

Maker and developer Rolf Hut has created an awesome Arduino powered longboard which is equipped with LEDs that react to the speed of the rider and board. Hut has used 4 x magnets and a Hall effect ...
