[Noisebridge-discuss] victor 883 Motor controllers/ Arduino

[davidfine]

The short answer is YES, these can be driven from an arduino. Generate 
the PWM signal with analogWrite()
The longer answer is they use PWM aka pulse width modulation so set the 
speed, and arduinos can output that signal.  See 
http://www.arduino.cc/en/Tutorial/PWM

The docs for the IFI say you may require a "PWM Signal Driver" if you're 
using your own controllers to drive it. That probably just means you 
need to step up the voltage that the arduino puts out to meet the 
operating voltages of the IFI. It says it operates at 6-30V, but i 
wouldn't be surprised if the 5V from an arduino will sufficiently drive 
the PWM signal. If it turns out to require higher voltage, buy an 
appropriate "PWM Signal Driver" IC, or just use a transistor.
