Sensor-Triggered Toy Race Car Timer

From the creator

Racing toy cars, like Pinewood Derby or CO2 dragsters, is a lot of fun. But if you want to compare the results of multiple races, you need be able to accurately record the finishing times of each one. To do this, I designed a timer circuit that will automatically record the finishing times.
