For an out-runner to my HEMTT project, I want to power this dual-motor ( http://www.robotshop.com/tamiya-double-gearbox-70168.html
) with a cheap/small arduino, using Bluetooth via amarino, and stick it in this -> http://www.robotshop.com/tracked-vehicle-chassis-kit-4.html
, then make a simple sheetmetal hull (the math is easy) so it can float.
Basically, making an ARGO type vehicle. I'd be running it off a 7.2 NiMH pack.
How would I run the low-voltage motors with the arduino? I assume the arduino will be fine running off the 7.2, it's stepping down to the 1.5 for each motor I'm not sure about. Each motor pulls 0.66 amps.
