I'm having a hard time getting the dual motor controller shield to work. I'm using the MotorDriverBasic.ino example in the TinyCircuits-TinyShield_Motor_Library-master.zip download. I put some serial port writes in the loop to confirm that the motor example loop is running. It looks like it is running. I also tried another older example code I found online.
I was able to swap out the motor shield for the servo shield and get the servo shield to work with the ServoDriverBasic.ino example, so I think at least part of things are working (the servos I plugged into this shield move back and forth as expected).
Any suggestions would be much appreciated. It feels like maybe there is some step I missed??
