Overview
Learn how to control a Servo Motor with Raspberry Pi Pico W Microcontroller with this detailed tutorial. We’ll be using Pulse Width Modulation (PWM) on the Raspberry Pi Pico to manage and direct the Servo Motor’s movements.
Pulse-width modulation (PWM) is a technique to control the strength of digital signals, essential for managing devices that need power. This tutorial goes into PWM generation, demonstrating the Raspberry Pi Pico RP2040 microcontroller’s abilities. Discover how to create a variable PWM signal, a crucial skill for adjusting the speed of DC motors and fans.
This guide takes you through the basics of PWM while working with a Servo Motor. You’ll also understand how to connect a Servo Motor to the Raspberry Pi Pico RP2040 Microcontroller. Using MicroPython code and the Servo library, you can easily rotate the Servo Motor in any direction you want.

Servo Motor
Servo motors are widely used for their easy rotation control. Featuring a geared output shaft that turns precisely one degree at a time, these motors have signal pins for control in addition to power pins. The SG-90 Micro Servo Motor is a compact, high-power option, rotating approximately 180 degrees. Compatible with various servo code and libraries, it’s an excellent choice for robotics and other applications.
