Description: This is an other kind of a LED Chaser in which the 'PIC16F84A' microcontroller, IC1, is used. 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. Resistors R9-R13 provides a pull-up for the input connected to switches S1-S5. 4 MHz crystal is used for clock pulse generator & capacitors are used to ground the unwanted pulses.
