Does the GoPiGo (or BrickPi/GrovePi) support VEX sensors?
We haven’t tried hooking them up. In theory though, you should be able to do it.
Looking at this page for Vex Sensors, it seems that almost all of their sensors are analog. That should be pretty easy to program around, but you’ll have to come up with an adapter for the Grove connectors to the Vex connectors.
