Arduino Code for Controlling the Servo Motor

1#include <Servo.h>

3Servo myServo;  // Create a servo object
4int xPin = A0;  // Joystick X-axis
5int yPin = A1;  // Joystick Y-axis (Optional for dual-axis control)
6int servoPin = 9;
7
8void setup() {
9    myServo.attach(servoPin);
10    pinMode(xPin, INPUT);
11    pinMode(yPin, INPUT);
12}
13
14void loop() {
15    int xValue = analogRead(xPin);  // Read joystick X-axis value
16    int angle = map(xValue, 0, 1023, 0, 180);  // Convert to servo angle
17    myServo.write(angle);  // Move servo to the mapped position
18    delay(15);  // Small delay for smooth movement
19}
