Arduino Servo Motor Code Using the Servo Library

The question

A servo motor's signal wire is on pin 10. Using the Servo library, move it to 90°, wait 1000 ms, move it to 135°, wait 1000 ms, and repeat.

The sketch

#include <Servo.h>

Servo motor;

void setup() {
  motor.attach(10);
}

void loop() {
  motor.write(90);
  delay(1000);
  motor.write(135);
  delay(1000);
}

Wiring

Servo: brown → GND, red → 5V, orange (signal) → pin 10.

How it works

1. 1#include <Servo.h> and Servo motor; create a servo object.
2. 2motor.attach(pin) connects it to the signal pin.
3. 3motor.write(angle) turns it to that angle; the delay gives it time to get there.
