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 ...

I made this project because I wanted a way to automatically control ... 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 ...

[tinyboatproductions] introduced an Arduino Nano and a buck converter, both of which were admittedly a bit overkill. Now the speed can be controlled with a pot. Once control of the fan was sorted ...

It’s used in the CNC mill he build and he figured, why not add the ability for the computer to control the speed ... demonstrates an Arduino driving the servo based on a potentiometer input ...
