Hi all, I´ve been using an Arduino for a while now, but I´m running into some problems.
I got a DFRobot motorshield (http://www.dfrobot.com/wiki/index.php/Arduino_Motor_Shield_(L293)_(SKU:_DRI0001
)) connected to my Arduino, and 2 lego motors to the shield. I connected the shield and motors just the way it should, so there is no problem there.
Whenever I set the directional port of Motor 2 (pin 4) to LOW, the motor doesn't do anything. If I do the same for Motor 1 (pin 7) the motor does turn the other way.
My best bet is that the shield is broken, but I'd like to know what you guys think.
