I will attempt to dig this out and photograph it for you - maybe a diagram. Everything is dismantled and boxed, although I'd love to resurrect the project as a portable, modular rally stage at some point.
In the meantime, these are the clearest images I can find from the archives...
First, the relay being tested with a 5V DC power input and output going to drive a motor
Where the blue & white pair (top right) is coming in from the deadstrip...
And then hooked up to the Arduino...
With power coming from the Arduino itself (red & black) and 'lap sensing' output to the Arduino (orange and yellow).
