A few months ago I posted about making a wire sorter. You can read the thread here
https://forum.arduino.cc/?topic=705745#msg4748155
I finally had a chance to try it out, and it was successful.
The photo shows the sending unit attached to approximately 12 wires. The sender can attach to up to 16.
The receiver was located about 30 feet away. I was able to identify 11 wires including one that was open.
Both sender and receiver use a 4 AA battery pack with on off switch that I purchased with the DC plug attached
for the UNO power input ( I believe I purchased from DigiKey ).
Obviously all power was locked out before using this.
Thanks for the help and ideas. Only thing left is to make cases for 2 units.
