Hello Roddy Wayne,
It is a matter of measuring the voltage drop across a known resistance, the more voltage lost, the higher the current being used by the load. I would use the ADC to measure the voltage on both sides and subtract the lower from the higher. Build a lookup table with PWM duty cycle calibrations.
