Pardon my ignorance, when you say "under load", do you kean the motor connected with all its final resistance such as gears and tracks?
Also, I was not planning to go as far as digital control. This is a cheap, but important project and I hope I can get it running. —Mike M Message sent by way of mobile device On Nov 22, 2009, at 6:03 PM, Frank Pittelli <[email protected]> wrote: > Mike Mane wrote: >> Anyway, the tank is powered by two 9VDC gear-motors, and I would like >> to be able to control the trim of these engines to ensure >> equilibrium. >> Can this be done with a potentiometer on each circuit?
