{{Introduction
|Introduction=<translate>Servo motors are widely used in robotics, automation, and DIY projects because they allow precise control of angular position. The Arduino Nano, being compact and versatile, is perfect for controlling servos in space-constrained projects. In this tutorial, we’ll learn how to connect and program a servo motor with the Arduino Nano</translate>

|Step_Title=<translate>Understanding the Servo Motor</translate>
|Step_Content=<translate>'''Wires:'''

* '''Red''' → VCC (typically 5V)
* '''Brown/Black''' → GND
* '''Orange/Yellow''' → Signal (PWM input)

'''Working Principle:''' The servo motor rotates to a specific angle (0°–180°) based on the PWM signal sent from the Arduino

Circuit Connections

* Connect '''servo VCC (red)''' to '''5V pin''' of Arduino Nano
* Connect '''servo GND (black/brown)''' to '''GND pin''' of Arduino Nano.
* Connect '''servo signal (orange/yellow)''' to '''digital pin D9''' of Arduino Nano (you can choose other PWM-capable pins).
* If using a high-torque servo, power it with an '''external 5V supply''' and connect grounds together to avoid damaging the Nano</translate>

|Step_Title=<translate>Installing the Servo Library</translate>
|Step_Content=<translate>The Arduino IDE comes with a built-in '''Servo.h library'''.

* Open Arduino IDE → Go to '''Sketch > Include Library > Servo'''.
* This library simplifies sending PWM signals to the servo.
<syntaxhighlight lang="c">
#include <Servo.h>

Servo myservo;  // create servo object to control a servo
// twelve servo objects can be created on most boards

int pos = 0;    // variable to store the servo position

void setup() {
  myservo.attach(9);  // attaches the servo on pin 9 to the servo object
}

void loop() {
  for (pos = 0; pos <= 180; pos += 1) { // goes from 0 degrees to 180 degrees
    // in steps of 1 degree
    myservo.write(pos);              // tell servo to go to position in variable 'pos'
    delay(10);                       // waits 15 ms for the servo to reach the position
  }
  for (pos = 180; pos >= 0; pos -= 1) { // goes from 180 degrees to 0 degrees
    myservo.write(pos);              // tell servo to go to position in variable 'pos'
    delay(10);                       // waits 15 ms for the servo to reach the position
  }

|Step_Title=<translate>Uploading the Code</translate>
|Step_Content=<translate>* Connect Arduino Nano to your PC via USB.
* Select '''Tools > Board > Arduino Nano'''.

* Choose the correct '''Port'''.

* Click '''Upload'''.
* The servo should start sweeping back and forth.</translate>

|Step_Title=<translate>Testing and Troubleshooting</translate>
|Step_Content=<translate>* If the servo '''jitters''', provide external power.
* Ensure '''common ground''' between Arduino and external supply.
* If the servo doesn’t move, check wiring and pin assignment.
* Use <code>myServo.write(angle)</code> to set specific angles (e.g., <code>myServo.write(90)</code> for center position).

=== Expanding the Project ===

* Control servo with a '''potentiometer''' for manual angle adjustment.
* Use '''ultrasonic sensors''' to make the servo respond to distance.
* Integrate with '''Bluetooth/Wi-Fi modules''' for remote control.</translate>
