What is Accurate Electronic Stop-Watch Project about?
This circuit can be used as an accurate stopwatch to count up to 100 seconds with 0.01 second resolution or up to 1000 seconds with 0.1 second resolution. A stable 1MHz crystal frequency is divided through counters to produce a final frequency of either 100Hz or 10Hz for displaying time on a 4-digit LED display. The stopwatch can be started, stopped, and reset using three switches to time sports and other activities with accuracy.
