Automated Testing of 3.5mm AT Jacks

At ATMakers, we use lots of AT Jacks.  Every switch-adapted toy, every interface device, almost everything we make requires a 3.5mm jack or plug.

Because of this, we ask STEM programs and Robotics teams to make us jacks and plugs as their first soldering project, and we’re always making them here.  Therefore we have lots of jacks, and we need to do lots of testing! This project makes that simple!
