Arduino Stop Watch with Laser Pointer trigger

Here’s the video:

EtherTen plus a DMD display (from Freetronics) connected to a simple LDR and laser pointer. Reports times back to computer for easy recording. Next step is to create a bunch of these on the same network, so there can be a start/stop/midpoint and multiple displays. All configurable from a central computer (ie: laptop on the same network).

Here’s the code on github:
