DC motors (brushed)
===================
DC motor (brushed) is a motor that rotates when a DC voltage is applied to its terminals.

Servomotors
===========

A servomotor is a motor that can be controlled to rotate to a specific angle. Actually, it is a DC motor with a built-in feedback 
mechanism that controls the speed and position of the motor.

.. note:: 
   To drive electrical motors, you need to use a motor driver. See :ref:`Motor Drivers <motor_drivers>`.
