this is my fake zipper test. I put in 10 220ohm resisters and used staples as my "zipper" to connect the switch from the power to one resister that sent power to the LED and light it up! This is to test the zipper setup and show the movement of the signal as the zipper moves down.

Also note the resisters are wound around a jewelry tool to make loops for easy sewing attachment with conductive thread. :)
