Sorry to be buly, but using your PNP transistor is useless in the case you show. It does not prevent the motor to pull too much current from Arduino, if the motor is too strong. It is better to get used to having the motor feed from an external source, rather than from arduino, in case the motor is too big. Just keeping the base of PNP connected to Arduino is less risky.

Hello, first, thnak you a lot for your instrtables. It is the first ever i read about bike speedometer, and you taught me about the hall effect sensor.But I am not sure to understand why there is no magnet attached to some of the spokes, and how your sensor is rated and taken into acount by your code. Does it detect every spoke that passes by, which means you then divide the frequency of detection by the number of spokes to get the rpm ?
