Step 4Complete the wiring

Complete the wiring
Using epoxy, glue each IR sensor into place on the interior back of the U-channel. Daisy chain all the plus-wires together by using the wire butt connectors. Do the same with the minus-wires of the IR sensors. Then, cut a length of wire to connect to each of the data cables of the IR Sensors. Now fasten each data wire to one of the wires you just cut.

Use zip ties to tuck the wires tucked away, but leave enough slack so they don't pull out of the IR sensors. Use your multi-meter to test the connections. Once it's working, disconnect the wires.
