PIC16F628a Led Chaser
Description: The heart of the LED chaser is the 'PIC16F628A' microcontroller, IC2. The program that runs on this chip controls the LEDs attached to the output port pins. Resistors R1 - R8 limit the current through LED1 - LED8 to a safe level. Resistor R9 provides a pull-up for the input connected to switch S1.
