Hot Wheels Electronic Finish Line with Arduino Nano and Light Sensors

I made a Hot Wheels car finish line for my son. The Arduino controlled sensors are connected to my Laptop running a Processing sketch. “Winner, Lane One!”

All code and circuit is included in the write-up here:

I am going to be developing this into a wireless version, using ESP8266 and Processing for Android. Inspired by “Hot Wheels ID”, the new augmented reality Hot Wheels product.

Let me know what you think!
