Servo Motor SG90

Servo motors are great devices that can
turn to a specified position. They have a
servo arm that can turn 180 degrees. Arduino, we can command servo to go
to a specified position and it will go
there. As simple as that! Servo motors
were first used in the Remote Control
(RC) world, usually to control the
steering of RC cars or the flaps on a RC
plane. With time, they found their uses in
robotics, automation, and of course, the
Arduino world.
