Week 8 lab: digital alarm clock


The student will construct a digital alarm clock using basic logic components. The clock will consist of a timer circuit, a divide by 6 counter, a decade counter, and a display module. The alarm will be set by switches in BCD notation and the alarm itself will be instrumented by attaching a light which will illuminate when the alarm time and the clock time match.

The circuit will use the following components:

Timer (555)

7 segment display
