What is a Servo Motor

Servo motors are versatile and widely used in various projects due to their precise control over angular movement. The SG90 servo motor, particularly, is popular among hobbyists and professionals for its compact size and reliable performance. Understanding the servo motor pinout is crucial for proper connections, as it typically has three wires: power, ground, and signal. When working with Arduino, the servo motor connection is straightforward. You connect the power wire to the 5V pin, the ground wire to the GND pin, and the signal wire to a digital pin on the Arduino. The servo motor working principle involves receiving a control signal that determines its position, making it perfect for applications requiring accurate movements.

Connecting the Servo Motor to the Arduino

Connecting a servo motor to an Arduino is easy and enjoyable for beginners. First, connect three wires: power, ground, and signal. The power wire should go to the 5V pin on the Arduino while the ground wire connects to the ground pin. Attach the signal wire to one of the digital pins on the Arduino. Follow these steps to provide the servo motor with the correct amount of power and precise control. This setup allows you to manage the motor’s position accurately and effectively.

After setting up the hardware, upload the Arduino code for the servo motor. The code is straightforward and typically uses the Servo library in the Arduino IDE. You start by including the Servo library, then create a Servo object. In the setup function, you attach the servo object to the pin to which you connected the signal wire. You can write the code in the loop function to move the servo to different positions. This simple code helps you learn the basics of servo motor interfacing with Arduino and can be a stepping stone for more complex projects.

how to connect servo motor with arduino

To connect a servo motor to the Arduino Uno R3, you’ll need a few essential components:

  1. Arduino Uno R3 board
  2. Servo motor
  3. L293D motor driver module (or any compatible motor shield)
  4. Jumper wires
  5. Power supply (e.g., a 9V battery or a regulated power supply)

First, connect the Servo motor’s Ground (GND) and Voltage (Vcc) pins to the same pins on the L293D motor driver module. Then, hook up the Servo motor’s signal pin to any output pin on the motor driver module, such as OUT1. In the next step, specify the L293D module to the Arduino Uno R3 with the correct digital and power pins.

Servo Motor Arduino Code

Controlling a servo motor with Arduino is a simple and fun project for beginners. The right Arduino code allows you to easily control the motor’s movements. A servo motor controller sends precise signals to guide the motor to its desired position. With Arduino, you can write straightforward code to adjust the servo’s angles and movements. This project is perfect for learning the basics of electronics and programming and prepares you for more advanced projects later on.

Grab an Arduino board, connect a servo stepper motor, and use jumper wires to set it up. First, use the Servo library to control the motor, which makes managing it simple. Then, upload the code to your Arduino and experiment with different angles and speeds. This process is both fun and educational. Moreover, using a servo motor with Arduino opens up many creative possibilities, such as building robot arms or rotating platforms.

You must write code to control the servo motor with the Arduino Uno R3. Here’s a basic example given below  that demonstrates how to move the servo stepper motor to a specific angle:

“`arduino

#include <Servo.h>

Servo myServo; // Create a Servo object

void setup() {

  myServo.attach(9); // Attach the servo to pin 9

}

void loop() {

  myServo.write(0); // Move the servo to 0 degrees

  delay(1000); // Wait for 1 second

  myServo.write(90); // Move the servo to 90 degrees

  delay(1000); // Wait for 1 second

  myServo.write(180); // Move the servo to 180 degrees

  delay(1000); // Wait for 1 second

}

“`

In this piece, we first import the ‘Servo.h’ library, a set of functions required for servo motor driving. In the first step, we create a ‘Servo’ object and name it ‘myServo’. Then, we change its PIN to PIN 9 so that the servo’s movement will be based on the feedback of the pin.

The ‘loop()’ function houses the logic of the servo motor execution control. We use the ‘write()’ function to specify the angle to which the servo stepper motor should move. The servo motor moves in the following sequence: to 0 degrees, 90 degrees, and finally, 180 degrees. It pauses for one second while moving from one position to the next.
