I'm very new to Arduino and have been working on a project involving a 6V DC motor. I purchased a motor shield and everything was working fine, but I think I may have typed something incorrectly into the code as suddenly the motor stopped working. For a little bit, it would still turn for perhaps 3 seconds then stop.
Now, with or without the motor shield, none of my various sized/type motors will work, even in the most basic of layouts. However, I can still do basic projects involving LEDS. Does anyone have any ideas as to what might be damaged or problematic? I would really appreciate your help with this, as I'm kind of at my wits' end.
