servo motor 90 degree rotation code

When you’re working on a project that requires precise control over movement, a servo motor is often the go-to solution. Whether you're building a robotic arm, a camera gimbal, or a small-scale automation system, a servo motor can make all the difference. But how do you make a servo motor rotate exactly 90 degrees? That’s where the magic of code comes in.

Now, let’s talk about what makes a 90-degree rotation so crucial. For many projects, you need precise control over a motor’s rotation, whether for positioning, speed regulation, or specific angles. A 90-degree turn is a common and straightforward task for a servo motor, and with just a bit of code, you can make it happen in no time. But how do you get started?

First off, let’s clear up the basics. A servo motor operates on pulses sent from a controller, which is usually a microcontroller like an Arduino. These pulses tell the servo to move to specific angles, and the duration of the pulse controls the position of the motor. For a 90-degree rotation, you’ll typically send a 1.5-millisecond pulse to the servo (the middle position). However, moving it 90 degrees requires a little more detail.

In terms of code, here’s a basic sketch to get you going with an Arduino:

#include <Servo.h>

Servo myservo;  

void setup() {
  myservo.attach(9);  // Pin connected to the servo
}

void loop() {
  myservo.write(90); // Rotate servo to 90 degrees
  delay(1000);       // Wait for 1 second
}

This simple script does exactly what you need. It attaches the servo to pin 9, then moves it to the 90-degree position. The delay ensures the motor stays in position for a second, giving it enough time to complete the rotation. You can easily modify this to suit your needs—whether it's adjusting the position or changing the delay.

But, here’s the question that comes up often: What if I need to control the speed of the rotation? That’s where things get interesting. In most cases, a servo motor will rotate from one position to another at a constant speed, but if you want to control how fast it turns, you’ll need to introduce more advanced techniques. For instance, using a loop to gradually move the servo in smaller increments can give the illusion of a slower, smoother rotation.

Here’s how you might write code to gradually move the servo to 90 degrees:

#include <Servo.h>

Servo myservo;

void setup() {
  myservo.attach(9);
}

void loop() {
  for (int pos = 0; pos <= 90; pos++) {
    myservo.write(pos); 
    delay(15); // Small delay to slow down the movement
  }
  delay(1000);  // Wait before starting again
}

This little tweak allows you to see the servo gradually move to 90 degrees. The delay of 15 milliseconds between each increment slows it down, making the rotation appear smoother and more controlled.
