Re: ardumoto, help needed

It's possible that the motors that you are using draw too much current, causing problems with the power supply to the Arduino. Does the code work with a multimeter in place of a motor?

Small DC motors can draw a lot of current, and if this is from the same supply as the Arduino (which is how the Ardumoto board is originally setup), then the Arduino may not run reliably (eg it may reset when it switches on the motors).

I've been using the Ardumoto with the Tamiya gearbox successfully - you can read more about it (along with some sample source code) here: To minimize glitches, I ended up running the motors on a separate supply to the Arduino. I did this by bending the Vin pin outwards...
