    This document provides a circuit diagram for an 8-channel LED chaser project using a PIC16F628A microcontroller. The circuit includes 8 LEDs, resistors to limit current to the LEDs, a pushbutton switch, a 5V voltage regulator, and capacitors for power filtering. The microcontroller controls the LEDs in a chasing pattern by turning each one on sequentially in response to the pushbutton or an internal timer.
