what reading do you think I should focus on? The rpm or current the motor is drawing?
But how do I keep the rpm constant? If I for example run the motor on full speed(analogWrite(255)......)
However, car and motorcycle manufacturers break in instructions suggest that you should vary revs during the break in period. Indeed, they suggest that running at constant revs is a bad thing.
How do I measure the current the motor is drawing. Can I use one of the analogue ports??
