I just learn raspberries pie, write the program of motor speed, the principle of clear, was just start when there is no speed motor, then measure the, with input and output of hall sensor value feeling then print directly with magnet near the hall sensor will not trigger sensor, when the magnet speed enough to set out, input the value of both turn don't turn always is zero, no magnets is 0, speed can be measured, but no response to low speed, the return value of hall sensor is confused, still hope you glad, thank you
