Hi, I'm trying to drive a DC motor with this motor driver: http://www.seeedstudio.com/depot/l298-dual-hbridge-motor-driver-p-284.html?cPath=170_173 The problem is, that when it's all powered from USB only (using only a small motor without load) everything works fine and I am getting serial readout…

Serial communication fails with motor driver using external PSU

There are current limitations to the Arduino hardware.
