  • Pardon my noob question… but I bought this to use it with an Arduino Diecimila and I’m able to run it by connecting it’s 4 control pins to 4 digital outs on the Arduino. However, that leaves 2 pins remaining which I assumed I could attach to a 9V power adapter for greater torque… however attaching power doesn’t do anything. Am I missing something huge? How do I connect power to this? The datasheet doesn’t label those 2 other pins as + or -.

No public wish lists :(
