Using this DG01D - E hobby motor is quite simple. First, connect it to a power supply with a voltage between 3 - 9V. Make sure to set the positive and negative voltage according to your single - chip microcomputer's power supply voltage, which is commonly 3.3V or 5V. Remember, you need at least two motors if you're working on a robotics project. When the motor is running, the hall sensor will detect the magnetic poles of the plate. If you want to know the motor's position or speed, you can check the hall output level. As for maintenance, keep the motor clean and avoid exposing it to moisture or dust. If you notice any unusual noises or malfunctions, stop using it immediately and check for loose connections or damaged parts.
