Hello All,
I've searched via the forum search and via Google but have been unable to find much discussion so far about robotics in a school environment, so I'm sorry if any of this has been asked before.
What's the best way to go about controlling motors from the Raspberry Pi? Does anyone make USB plug-in motors that I can power via a USB hub and control with simple start() and stop() functions? Or do I have to use a separate (hopefully USB-controlled) relay device of some sort?
The same goes for sensors: does anyone make handy plug-in-and-go USB sensors for light, temperature, etc?
