Serial Controlled RGB LED PWM Driver PIC12F629 based PWM controller for RGB LEDs

Leave a Comment / Using Pic Microcontroller / By

Description If you want to build your own multiple RGB LED display that you can control from either a PC or a dedicated controller then this project will let you do just that. The project on this page came about when while I was developing a more complex intelligent driver. During that work I put …

RGB LED PWM Driver for High Power 350mA LEDs using PIC12F629

Leave a Comment / Using Pic Microcontroller / By

Description This project combines a PIC and three constant current ‘buck’ converters to produce an RGB LED controller that will operate with the the high power 350mA LEDs using PWM to control the LED brightness.  By driving the red, green and blue LEDs with varying pulse widths the controller can generate up to 16 million colours using …
