I bought the 12 channel Pololu from amazon. I downloaded the Pololu program and installed on my computer. I took usb cable with 4 wire and connect to Pololu the green and the red wire. And I connect a few motor to Pololu . I open the program to try to move the motor I see the program identified the Pololu at the bord but nothing happened when I want to return the motor in the program. What I have to do?
