I'd like to make tool for identifying multiple wires using an arduino "transmitter" board and a laptop or pda(preferrable) "receiver". Basically, I'd like to run a coded signal through up to 10 different wires (each lead is a valve station) at around 12V (I'm pushing signal through 14 gauge wire over 500' sometimes) with a single common.
I'm wondering which board would be the best platform to base this project on. Any suggestions? I'd also like to power the transmitter side with batteries.
Thanks!
