1. Display emits the speed signal, which travels from the ribbon cable to the drive board.
2. The drive board puts out power for the motor. (The transformer splits power into smaller
voltages for various circuit operation. The inductor ensures steady current to the motor.)
3. The motor operates according to power from the drive board.
4. The optic sensor clocks motor movement. Its signal travels from the sensor, to the drive board,
up the ribbon cable, to the display.
5. The display program IC uses the speed signal from the optic sensor to determine whether to
command the drive board to supply more or less voltage to the motor.
