RGB LED PWM Driver


Posted on Apr 24, 2012

The circuit uses (RGB) Red, Green and Blue high brightness LEDs that are pulse width modulated (PWM) to vary the intensity of each colour LED. This allows effectively any colour to be generated with rapid changing strobe effects, fast and slow colour fades as well as static colours. The data used to set and change the colours is held in an easy to edit file so if you don't like the sequences provided with it, you can modify the sequence data include file yourself and reprogram with your own sequences. The code can be assembled for use with the following PICs: 12F629, 12F675, 12F683. Just select the correct processor in the MPLAB IDE before assembling.



The LEDs listed above are those I used in the build photo's on this page, however you can use almost any 5mm high brightness LED with this design. Your choice of LED's really depends on what you want to do, how much you want to spend and so on. I've b
