Hi.
Using PWM to control a motor has the same affect as lowering the voltage, and I wondered if any one could think of a way of measuring (in the circuit) the 'apparent' voltage - i.e. the voltage that would be needed to make the motor spin at that speed.
Or measure when the duty cycle went beyond a trigger point.
Not for any particular project, just thought process going around in my head.
Cheers,
Tim
