4 RGB LED PWM Controller using PIC16F628

If you are looking for a new microcontroller project and like to play with LEDs this 4 RGB LED PWM Controller project might be for you. There is full documentation provided.

"The advantages include the built-in 4MHz oscillator, hardware USART, and ease of reprogramming.  A couple of features I had in mind during the design:

1. Multiple intensities for each color (using PWM)
2. Multiple individually controllable RGB LEDs
3. High-speed update rate
4. Daisy-chainable and addressable
5. Simple serial control"
