    how did you measure the rpm of the motor and how did you tell if you reached overload with the motor stalled?

    • Thx

      I used an optical sensor. The first microcontroller counts the pulses from the sensor, the second drives the motor. When the first microcontroller cannot receive any pulse from the sensor, for 2 seconds, the motor was blocked. In this case the second microc. stops the driving signal for the motor.
