The servo motor utilizes a regular AC or DC motor couples with a position feedback device. ⇒ Gear Box Assembly to reduce motor speed This system comprises several parts such as Basically, the Servo motor is a part of a closed-loop system. So, in this article, we are going to see What is a Servo Motor? How does it work? Types of Servo Motors and Applications where it is used.Ī servo motor is an electric motor that can rotate with great precision and high efficiency. Servo Motors are the perfect mechanism to achieve these accurate movements. In all these applications one thing is common that the precise and accurate linear and angular movements. There are plenty of other applications like automatic door opening/closing, antenna positioning, solar panel movement, etc.

We often see printer printing a paper and see the accurate movement of the printing head on the paper to write or draw. we start the function by attaching the servo object created to pin D8 of the microcontroller, after which we center the servo, turning it to zero degrees.We have seen the working of robotics arms in many industries and most of us thought that how these arms move very precisely. With this done, we proceed to the void setup() function. Next, we create an object of the library, to be used as a reference for controlling our servo motor throughout the code.

We start the code for the project by including the libraries that we will use which in this case is the servo.h library.

The library comes pre-installed in the Arduino IDE removing the need for us to download and install. The library makes it easy to turn the servo at different angles using a single command. The code for this project is quite easy thanks to the very comprehensive and concise servo.h library developed by the Arduino team to facilitate the use of servo motors in Arduino projects. With the connection all done, we can now proceed to write the code for the project. Servo directions are sent from the microcontroller to the servo motor as PWM pulses.

The signal pin was connected to the digital pin 8 of the Arduino because it is a PWM pin.

Schematicsįor emphasis, the connection is further described below. The Signal pin is the one used to feed the control signal from the microcontroller to the servo, to get the servo rotate to a particular angle.Ĭonnect the Servo to the Arduino as shown in the schematics below. Servo motors generally have three pins/wires, this includes the VCC, GND, and the Signal pin. The schematics for this project is quite simple as we will be connecting just the servo motor to the Arduino. The following components are required to build this project:Įach of these components can be bought via the link attached to them. Since we will be using just one servo in this tutorial its fine to power it with an Arduino. Servo’s have high current requirement so when using more than one servo motor with the Arduino, it is important to connect their power connections to an external power supply as the Arduino may not be able to source the current needed for the servo. For this tutorial, we will be using the popular SG90 servo motor and our goal will be to rotate the servo motor from one end to the other.
