Name

write()

Class

SoftwareServo

Description

Moves a servo motor to a given orientation

If you are using this class in combination with a continuous rotation servo, different angles will result in the servo rotating forward or backward at different speeds. For regular servo motors, this will instruct the servo to rotate to and hold a specific angle.

Examples

  • import processing.io.*;
SoftwareServo servo;

void setup() {
  servo = new SoftwareServo(this);
  servo.attach(4);

  // On the Raspberry Pi, GPIO 4 is pin 7 on the pin header,
  // located on the fourth row, above one of the ground pins
}

void draw() {
  // we don't go right to the edge to prevent
  // making the servo unhappy
  float angle = 90 + sin(frameCount / 100.0)*85;
  servo.write(angle);
}

Syntax

  • .write(angle)

Parameters

  • angle(float)angle in degrees (controls speed and direction on continuous-rotation servos)

Return

  • void
