We were assigned with the task of designing and building a digital clock that displays the time in Binary. First a power supply that outputs a 60Hz square wave is fed into the circuit. We used 74160 decade counters in the project. A 74160 divided the clock down to 6Hz‚ and then a truncated 74160 divided it down to a 1Hz wave that would be the input for the clock. This clock will display in military time. The 1HZ is equal to one second and is fed into the first 74160. There are six 74160 counters
