Analog Slot Car Lap Counter (Single Lane)
This PCB will allow you to build a lap counter for your slot car track.
This was designed to be used with an arduino at 3.5v
Should work at 5v but not tested.
There is a line in for high to low break.
If your sensor is high (3 to 5 v) and drops to zero when the car breaks the sensor use this.
There is also a line in for low to high break.
If your sensor is low (zero) and jumps to High (3 to 5 v) when the car breaks the sensor use this.
