Hello.
I am trying the “Minimal wiring diagram” and control the stepper motor with a Arduino.
I fail to get any readings or any sign of life on the motor controller pins: 1a,1b, 2a and 2b.
This is the setup:
//jumper reset and sleep together
//connect VDD to Arduino 5v
//connect GND to Arduino GND (GND near VDD)
//connect 1A and 1B to stepper coil 1
//connect 2A and 2B to stepper coil 2
//connect VMOT to power source (12v)
//connect GRD to power source (12v)
This is the sketch:

By the way: awesome video on the A4988 by Claire. That and very god information page on the product makes this problem even more frustrating
Tnx in advance
