In this lab we worked on building a stop watch. The objective was to build a stop watch that counts in seconds and 1/10 of a second to a maximum value of 99.9 seconds. It would use 4 control switches; a global reset switch, a start switch, a pause switch and another pause switch slightly different from the former. We were tasked to display the stop watch time on 7-segment displays. The design of the circuit was fairly straight forward to develop and used 1 module in addition to the main module.
