Servomotor – Raspberry PICO

A servo motor is a motor designed to maintain a precise position, determined by the user. This type of motor can move within a maximum angle of 180 degrees. Additionally, it is capable of providing a variable torque depending on the requested position.

Thanks to these characteristics, the servo motor is ideal for applications such as opening doors, valves, or managing the steering of a vehicle.

Here is the schematic for the servo motor with the Raspberry Pi Pico:

The servo motor works with a library that simplifies its use.

You can download it and refer to our course on libraries for installation instructions.

Here is the Arduino program to upload the code from the Arduino IDE:

#include <Servo.h>  // Includes the Servo library to control the servo motor

Servo myServo;  // Create a servo motor object

void setup() {
  myServo.attach(0);  // Attach the servo motor to GPIO0 of the Raspberry Pi Pico
}

void loop() {
  // Rotate the servo motor from 0° to 180°
  for (int angle = 0; angle <= 180; angle++) {
    myServo.write(angle);  // Move the servo motor to the specified angle
    delay(15);  // Wait a bit to allow the servo to reach the position
  }

  delay(1000);  // Pause for 1 second before starting the reverse motion

  // Rotate the servo motor from 180° to 0°
  for (int angle = 180; angle >= 0; angle--) {
    myServo.write(angle);  // Move the servo motor to the specified angle
    delay(15);  // Wait a bit to allow the servo to reach the position
  }

  delay(1000);  // Pause for 1 second before restarting the cycle
}
