Interfacing an Arduino to a Robo TX Controller

I use Arduino as a generic name for an embedded computing board. Other boards exist, as chipKIT and Wiring.

An Arduino features a 8-bit micro-controller. It is much less powerful than the Robo TX Controller, but also much cheaper. 

• WARNING AND DISCLAIMER
The sensors described in this section are not part of the fischertechnik system and can void the warranty.
Bad connection could damage your Robo TX controller.
Take the appropriate precautions.
You do it at your own risks.
