My new Motor Shield lights up red when connected to a Arduino Uno Rev 3. At this point I could only test it with a servo, which worked fine. Dont have any motors to test so could someone please tell me ( mayby a link to the functions of the LED ) if the LED should light green when connected to a controller? The Uno is powered by USB but I also tested it with a 9V external batterie, same effect, LED red...
