Hello,
I'm trying to control a Tronical Robohead. Thats a stepper motor, used for tuning a Guitar. Gibson uses it in their GForce series.

I think its a bipolar stepper-motor and I tried to control it with this code:
and this 4-pin circuit:

I can measure the PWM Signal at the stepper inputs but nothing happens. Has anyone an idea whats wrong?

I think its a bipolar stepper-motor and I tried to control it with this code:
Code:
#include <Stepper.h>
// change this to the number of steps on your motor
#define STEPS 100
// create an instance of the stepper class, specifying
// the number of steps of the motor and the pins it's
// attached to
Stepper stepper(STEPS, 20, 21, 22, 23);
void setup()
{
// set the speed of the motor to 30 RPMs
stepper.setSpeed(30);
}
void loop()
{
int val=200;
stepper.step(val);
Serial.println("new position");
}
and this 4-pin circuit:
