Scalextric Lap Counter Schematic for Arduino

Originally uploaded by Christhawkins

Here is my Schematic for a Scalextric Lap counter that uses and Arduino and Processing, the Arduino controls the sensors, LED's and buttons and it then relays the information via Serial to the Processing program. I have illustrated on the diagram a optocoulper but I had actual used a slotted Optical Switch (HA221).
