Topic: arduino and dfrobot motor shield (Read 669 times) previous topic - next topic


i have bought a dfrobot motor shield http://www.robotshop.com/eu/productinfo.aspx?pc=RB-Dfr-58&lang=fr-CA to control 4 motor with an Arduino (i have arduino Uno and Mega).
But i don't understand why when i clip them together (arduino and motor shield), nad when i put motor ON, all the others pins are put HIGH. :(
8) To solve this problem i connected wires between arduino and motor shield, and it work very well. So i want to know, if there are an other solution, because there are too many wires and it is not practice. :smiley-mr-green:
help me plz.
