My motor works on 12v.. So, I have the 12v dc going into the board and the motor is plugged in to 1to 4 . The jumpers are connected for channel a and b. When I run the arduino sketch "one turn" the motor works fine.. However, I want to use gbrl with it, so I have uploaded the gbrl sketch to my ardui...

I would like to connect the gbrl with the shield. It seems gbrl works from pin 1-4, but the voltage is too low to run the motor. pls help.
