Re: [Electric Boats] Re: Controller for 300w and microprocessor

 

The Arduino (about $30) does PWM as a standard part of its architecture. The question seems to be fitting MOSFETS (or whatever) on the motor controller side.

The simple way to do it is with a voltage controlled controller . then the interface can be a very basic digital to analog convertor circuit. the somewhat more technical way is to generate pulse width modulation in the micro.
