1. Small electric motors used in hobbyist projects that are powered by direct current and suitable for various applications such as model cars, boats, and planes.
2. An expansion board for a microcontroller that provides additional features to control motors.
3. The electrical potential difference that drives the current in a DC hobby motor, usually measured in volts.
4. Integrated circuits or modules used to control the speed and direction of motors.
5. A type of DC hobby motor that uses brushes to transmit electrical current to the rotating armature.
6. The flow of electric charge in a DC hobby motor, measured in units of amperes.
7. Safety feature that prevents damage to motors by cutting off power when current exceeds a set limit.
8. The rotational force produced by a DC hobby motor.
9. Motors that move in discrete steps, commonly controlled by motor shields for precision movements.
