Servo_pwm code change

IgnasPav

Hello everyone,

I am trying to change this code Servo pwm_code in Processing 1.0 from mouse control to simple code control same as it is in Arduino Sweep code.

Arduino code:

/* Sweep
 by BARRAGAN <http://barraganstudio.com>; 
 This example code is in the public domain.

*/ 

#include <Servo.h> 

Servo myservo;  // create servo object to control a servo 
                // twelve servo objects can be created on most boards

int pos = 0;    // variable to store the servo position 

void setup() 
{ 
  myservo.attach(9);  // attaches the servo on pin 9 to the servo object 
} 

void loop() 
{ 
  for(pos = 0; pos <= 180; pos += 1) // goes from 0 degrees to 180 degrees 
  {                                  // in steps of 1 degree 
    myservo.write(pos);              // tell servo to go to position in variable 'pos' 
    delay(15);                       // waits 15ms for the servo to reach the position 
  } 
  for(pos = 180; pos>=0; pos-=1)     // goes from 180 degrees to 0 degrees 
  {                                
    myservo.write(pos);              // tell servo to go to position in variable 'pos' 
    delay(15);                       // waits 15ms for the servo to reach the position 
  } 
} 

Processing code:

import processing.serial.*;

import cc.arduino.*;

Arduino arduino;

void setup() {
  size(512, 200);

  // Prints out the available serial ports.
  println(Arduino.list());

  // Modify this line, by changing the "0" to the index of the serial
  // port corresponding to your Arduino board (as it appears in the list
  // printed by the line above).
  arduino = new Arduino(this, Arduino.list()[0], 57600);

  // Alternatively, use the name of the serial port corresponding to your
  // Arduino (in double-quotes), as in the following line.
  //arduino = new Arduino(this, "/dev/tty.usbmodem621", 57600);
}

void draw() {
  background(constrain(mouseX / 2, 0, 255));

  // Output analog values (PWM waves) to digital pins 9 and 11.
  // Note that only certain Arduino pins support analog output (PWM).
  // See the documentation for your board for details.
  arduino.analogWrite(9, constrain(mouseX / 2, 0, 255));
  arduino.analogWrite(11, constrain(255 - mouseX / 2, 0, 255));
}

What should be void draw just to tell motor to move certain angle? Any help would be appreciated. Thank you Ignas
