Servo Motor<\/strong><\/p>\n

A servo motor is a rotary actuator or linear actuator that allows for precise control of angular or linear position, velocity and acceleration. It consists of a suitable motor coupled to a sensor for position feedback. It also requires a relatively sophisticated controller, often a dedicated module designed specifically for use with servo motors.<\/p>\n

Servo motors have been around for a long time and are utilized in many applications. They are small in size but pack a big punch and are very energy-efficient. These features allow them to be used to operate remote-controlled or radio-controlled toy cars, robots and airplanes. Servo motors are also used in industrial applications, robotics, in-line manufacturing, pharmaceutics and food services.<\/p>\n

Circuit<\/strong><\/p>\n

Servo motors have three wires: power, ground, and signal. The power wire is red, and should be connected to the 5V pin on the Arduino board. The ground wire is black and should be connected to a ground pin on the board. The signal pin is orange and should be connected to pin 9 on the board.<\/p>\n

The potentiometer should be wired so that its two outer pins are connected to power (+5V) and ground, and its middle pin is connected to analog input 0 on the board.<\/p>\n
