![]() ![]() ![]() Mostly microcontrollers or development boards have onboard 5 volts supply which we can use to power SG90 servos. Only 5 volts of power signal is required to power this motor. Vcc and ground, as their name suggests, are the power supply pins which are used to power servo motor. On top of that, it requires only one output pulse signal to control its movement. Moreover, it is small enough that it can easily fit into your robotics ARM or obstacle avoidance robotics projects. It can not move continuously but rotates up to 180 degrees and each step can be of maximum 90 degrees. SG90 is a low cost and high output power servo motor. Servo motor have many applications in robotics and industry for position based motion control system. It can easily control physical movement of objects due to its position controlled feature. Servo motor is a position controlled motor. ![]() Similarly in robotics, servo motor control mechanism is very useful to control position of robotics. Movement of objects can be controlled by controlling motion of motors. After that, we will look at how to interface it with Arduino and control its movement. Firstly, we will see an introduction of the servo motor. In this guide, we will learn about SG-90 servo motor and how to use them with Arduino UNO. ![]()
