How about an Electrical Test Box:
The test box will allow for easy debugging of electrical equipment and testing of electrical applications including motors, sensors, and batteries. An LCD will display variables in the programming including sensor values and battery voltage. Switches and pots will allow easy control and testing of devices. It will also be easily reprogrammable to allow for other applications such as autonomous motor and transmission tests. A Vex controller or an EDU bot controller would work well for this application.
