This light gate starts a timer when the touch sensor is depressed and stops the time when a vehicle passes trough the light gate. The time is then shown on the display and read aloud. Now I have to cut up a connector wire and solder another wire in between to set up the light gate at some distance. This will be the judge in the upcoming Drag Race Challenge here: meetup.com/De-Bonte-Mindstorms-Bouwers/events/172731772
