| Hello. | |
| I am trying the "Minimal wiring diagram" and control the stepper motor with a Arduino. | |
| https://www.pololu.com/product/1182 | |
| 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: | |
