All working except stepper motors - queenidog - 11-15-2015 07:47 PM

I have the OSC app installed and pushing the servo button causes the servo to cycle. I can see changes on the iPad on the serial monitor.

I don't have the robot built yet, so the gyro sensor is just sitting flat (horizontal) on the desk. If I move it around I get readings showing on the serial monitor. I thought this would be enough to trigger the motors into action but there is none whatsoever. I'm using CD player steppers for testing: 4 wire, small, known good, 5 volts op voltage.

I've also placed the sensor vertical as if the robot was laying down, waiting for a "rise-up" signal. After the 10 calibration, I move it horizontal but still nothing on the steppers, not even a "lock-up" with no movement.

Ideas?
