Micro Servo Motor SG90

Servo motors are the easiest to control as they already have an integrated board within. They don't require any external motor driver components. We simply plug it in the Arduino Board and control it with servo library. They can be use to create a steering mechanism for 4 wheeled robots. They can be used to control mini robot arms with low precision and low repeatability. We can attach for instance an IR Distance Sensor on top of it and cover a bigger area for simple object avoidance robot.
