Pulse Width Modulation is definitely the preferred method of dimming an LED with a microcontroller, but we were interested in hearing about a different method called Binary Code Modulation.

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 ...

The idea is to be able to effectively control the brightness of the ... a couple of them in stock. Using an IRFZ44N, I made a simple LED driver and used an Arduino Uno directly.

Now, I’d like to outline my random thoughts on better LED faders. So, if you want to regulate LED brightness ... of the Arduino, you often get displeasing jumps in your fades. If so, you can consider ...
