I am VERY new to all this and I am trying to build a pretty complex robot... My first step is just this:
I need to be able to connect 1-2 electric motors and 1-2 servo's to my computer through a single USB.
The motors and servos would need to be externally powered (through a single plug). I need to be able to control speed and direction.
That is all! Can someone point me in the right direction? Obviously I would like to do this AS CHEAP AS POSSIBLE.
