      Short description: In this exercise students will design a (very) light version of the digital watch – a stopwatch which counts seconds. It is started by designing a pure seconds’ counter, extended with control buttons for starting, stopping and continuing the stopwatch. The end result will not just be the system which counts seconds, but also the understanding how to extend this system to count minutes, hours and become a real digital clock.
