Arduino aims to provide a low cost and simple and easy path for the users to use devices that interact with the environment with the help of sensors and actuators such as in motion detectors and robotics etc. Servo motors are in limelight owing to their tremendous electrical performance and hence are being used in various applications. Servomotors have high torque capabilities. Servomotors are also known as control motors. Unlike large industrial motors, they are not used for continuous energy conversion but only for precise speed and precise position control at high torques. The main objective of this paper is to experimentally demonstrate the interfacing of a servomotor with the Arduino uno microcontroller board. The paper also emphasizes the working of servomotors and its salient features.
