Stop time with the clock controller

Return to Time is slipping away

This clock controller was designed to be an example of using "C" language to control timer interrupt, 7-segment LED and keyboard scanning. It provides 1-bit sink current driving output, for driving a relay. Many projects require 7-segment display and keypad interfacing may get the idea from the clock circuit and hardware.
