Here is an Arduino based circuit with three independent pulse width modulated (PWM) channels to fulfil your requirements! Just follow the schematic diagram to complete the construction, and use ...

Let’s start with the simplest led project which consists in turn on an LED. You can use an external one or use the one soldered on the board (pin 13). Turn ON an LED Sketch This is a very simple ...

Pulse Width Modulation is definitely the preferred method of dimming an LED with a microcontroller ... is that the more bits of precision you use, the faster your processor must run so that ...
