Hi,
I'm wanting to build a simple lap counter for my nephews scalextrics! I want it to be as simple as possible and if I can, I would prefer not to use adruino!
Does anyone know if it's possible to make the 7 segment display count up and cycle back to 0 with just 1 switch? If so, how?
I want to put the snap action switch in the groove on the scalextrics so that when the car passes the start/finish line, the cars leg that fits in the groove will press the switch and the 7 segment display will change!
Thanks, chris
