Summary of PIC16F628 RGB LED CONTROL CIRCUIT
This article describes an RGB LED control circuit using a PIC16F628 microcontroller programmed with JAL software. The system communicates via a serial port from a computer running Visual Basic code to send color data (red, green, blue) as three bytes. The microcontroller sequentially activates the LEDs for each color channel; persistence of vision makes them appear lit simultaneously. Source code and diagrams are available for download.

RGB CONTROL CIRCUIT DIAGRAM
This code is for a simple RGB LED controller for 8 LEDs using a PIC16F628. It is controlled by sending 3 bytes to the internal USART for the red, green, and blue color channels. The operation is very simple and so is the wiring. The PIC selects each LED then turns on/off the respective colors then goes to the next LED. Because of persistence of vision, the eye sees the LEDs as all being on at the same time.
