If we set the rotation angle is 90º to 160º then rotation starts from the 90º and goes up to 160º and returns to 90º and repeats this process continuously. If the required angle set in the program is 180° and the start angle is 0º then start rotation from 0º to 180º and then return automatically to oº and repeat this process. the shaft of servo goes to that angle and then returns. Auto sweep (without Potentiometer)ġst connection is for rotating in a fixed targeted angle. Here I am discussing some circuit connections of servo motor with Arduino UNO.

You may want a large, powerful one for moving the arm of a big robot, or a tiny one to make a robot’s eyebrows go up and down. Hobby servos come in a variety of shapes and sizes for different applications. Servo motors are also used in industrial applications, robotics, in-line manufacturing, pharmaceutics, and food services. radio-controlled airplanes to position control. Servomotor used in camera zooms, lift doors, or tools we may have at home. But Servos provide more torque than normal high rpm DC motor.Ī servo motor consists of three wires– a black wire connected to the ground, a white/yellow wire connected to the control unit and a red wire connected to the power supply. Their rotation is limited in between the fixed angles.Ī normal high speed tiny electric motor does not have much torque, but it can spin very fast. As the motor rotates, the potentiometer’s resistance changes, and then the control circuit regulates how much movement there is and in which direction also with precisely. The motor is attached with gears for controlling the wheel. Their rotation is limited between the fixed angles. The shaft of servos commonly does not rotate freely around similar to a DC motor, Servos are controlled by sending an electrical pulse of variable width or pulse width modulation (PWM), through the control wire. This is actually a DC Motor whose speed is slowly lowered by the gears. Servo motor is a type of motor that can move or rotate its shaft in a specific angle with high precision control of angular or linear position, velocity, and acceleration.
