Motor control with microcontrollers

Introduction

1. Servo:

At the most basic level, a servo is just a controllable motor. There are various types of servos. The Standard Servo is a geared down motor that has a limited range of rotation. It's principle is the same as stepping motor(cause it's kind of stepping motor).

And the characteristics of servo are high speed continuous range and close-loop control.

2. Microcontroller

It can be used to control motor and use it's internal function to cooperate the rotating torque and the load, thus reduse the work it need. Furthermore, it's good for long term operation by it's energy-saving merit.
