Trying to run Pololu Dual G2 High-Power Motor Driver 24v18 Shield for Arduino over a resistor (initially) using it as an arduino shield (Arduino uno)
using Simulink to control the Arduino
Unfortunately i am getting no current reading on my power supply when the input PWM is outputing at 5 V from the Arduino.
i can measure outputs on
Pin 9 - PWM arduino to board - can range the value 0-5V (Set to 5 V)
Pin7 - Motor direction - can switch 1 or 0 (set to 1)
Pin2 - motor sleep input - can switch 1 or 0 (set to 1)
can confirm that pins are working with mustimeter and reading expected value and have tried different conbinations of those values

Have also tried putting over a fan to see if that made a difference which it did not
Is there something i am missing here?
