I'm interested in using a DC motor as a sensor to measure hand-cranking speed. It seems like I could wire one lead of the motor to ground, wire the other lead to the sensor input with a resistor going to +5V. Is additional circuitry needed? Also, this method only measures one direction of rotation.…
