connect servo to arduino

To connect a servo to an Arduino, you will need to follow these steps:

  1. Connect the servo's power supply wire (usually red) to the 5V pin on the Arduino.
  2. Connect the servo's ground wire (usually black or brown) to the GND pin on the Arduino.
  3. Connect the servo's signal wire (usually yellow or orange) to a digital pin on the Arduino. Choose any available digital pin.

Once you have made the necessary connections, you can control the servo using the Arduino code. Here is an example code snippet to move the servo:

#include <Servo.h>

Servo myServo;

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
}

Make sure to include the Servo library at the beginning of your code. The attach() function is used to associate the servo with the specified pin, and the write() function is used to set the servo position in degrees.

Upload the code to your Arduino board, and the servo should start moving according to the specified positions in the loop() function.

That's it! You have successfully connected and controlled a servo using an Arduino.
