microbit servo motor code

If you’re working on a project that involves robotics, automation, or any hands-on tech experience, you’ve likely encountered the micro:bit. It’s a tiny, user-friendly tool that packs a punch in terms of functionality. One of the coolest ways to use a micro:bit is to control a servo motor. The connection is surprisingly simple, and the benefits are massive if you want to create automated systems, moving parts, or just explore the fascinating world of robotics.

A servo motor is essentially a small device that rotates to a specific angle based on the input signal it receives. So, when you combine this with the micro:bit, you get a setup where you can control physical motion with just a few lines of code.

So, how does the code work?

First, let’s break it down. A typical servo motor runs on a small electrical pulse signal. The micro:bit is perfect for generating these signals. You’ll need to use the P0 or P1 pin to connect your servo, and with just a bit of code, you can tell the servo to turn to a particular angle. Want it to move to 90 degrees? No problem. Need it to turn to 45 degrees? You’ve got it.

The basic code structure is pretty easy. Here’s a quick snippet:

from microbit import *
import machine

servo = machine.PWM(pin0)
servo.freq(50)  # PWM frequency

while True:
    servo.duty(512)  # 512 represents 90 degrees
    sleep(1000)  # Wait for 1 second
    servo.duty(1023)  # Rotate to the maximum position (180 degrees)
    sleep(1000)  # Wait for 1 second

In this code, you're using the PWM (Pulse Width Modulation) feature, which controls the speed and direction of the servo motor based on the duty cycle. In simpler terms, you're adjusting how much of the signal is on versus off, and that tells the motor how far to move.

Why is this so useful?

Whether you’re building a simple robotic arm or creating an automatic door, controlling a servo with micro:bit opens up a wide range of creative possibilities. You can automate processes, create cool interactive displays, or even experiment with your own robot designs. The best part? You don’t need to be a coding expert to get started. With micro:bit’s simple syntax and a bit of curiosity, you can go from zero to tech creator in no time.

Let’s talk about precision

One of the biggest challenges with servo motors is ensuring that they move accurately and respond well to code. This is where understanding the PWM signal comes in. You can control the degree of movement with incredible precision, which is perfect for projects where you need small adjustments. Plus, servos are usually pretty reliable, and when paired with micro:bit, they can work continuously without much hassle.
