Hacking Up the Senseta Robotics Platform
The R has been hack for the sake of wiring into an open platform. Geoff, LT and I spent friday afternoon setting up an arduino with code and libraries to control the motors on the robot. We reached the point where we were able to control the R's drive system.
The old, and closed, system and micro controller
Chopping it up, Open source here we come!

Great post Andy!

This example shows how to drive the motor with PWM using the analogWrite() function. The code starts out with the motors running full reverse and then steps them to full forwards
The circuit:
* Motor controller attached from digital pin 9 to ground.
