im trying to connect 2DC motor driver using arduino motor shield, tested
all the ioio output using led and it seems providing the desired output.
However, the 2 motor didnt move when i try to connect the ioio to the motor
driver. Im using a 9V battery for the motor. Is the motor driver not
compatible with ioio or it is other problem? my coding:
package ioio.examples.hello;
