How do a create a Processing program where I input numbers to adjust varaibles of the Arduino sketch ?

[ewanm2314]

I would like to use Processing to control the PWM of motors and also delay times. I am thinking of sending lists through Serial after inputting and the recieving that in Arduino IDE and for example:
setting variable2 as item 2 of list and so on.
I have already programmed a GUI in processing but am struggling with the serial part and whether or not my code works:

import controlP5.*;
import processing.serial.*;

Serial port;
ControlP5 cp5;
int motor1;
int motor2;

 void setup(){
 size(800,500);
  cp5 = new ControlP5(this);
 cp5.addTextfield("motor1").setColorBackground(0xffffffff).setColorValue(0x00000000) .setPosition(300,40).setAutoClear(false);
 cp5.addTextfield("motor2").setColorBackground(0xffffffff).setColorValue(0x00000000).setPosition(300,65).setAutoClear(false);
 cp5.addBang("submit").setColorBackground(0x00000000).setColorValue(0xfffffff).setPosition(300,95);
  printArray(Serial.list());
 port = new Serial(this, "???",9600);
 }
 void draw(){
 background(250,250,250);
 fill(0,0,0);
 textSize(20);
 text("motor",290,25);
 }
 
 void Submit(){
 print("submit request sent");
 motor1  = int(cp5.get(Textfield.class,"motor1").getText());
 motor2 = int(cp5.get(Textfield.class,"motor2").getText());
 }
 
 void motor1(){
   port.write('');
 }
 
  void motor2(){
   port.write('');
 }

Here is my arduino sketch code:

int repeatcycle = 2; 

int motor1speed = 50; 
int motor1duration = 1000; 
int pause1 = 1000;

 

int motor2speed = 50; 
int motor2duration = 2000;
int pause2 = 1000;


 


int cyclecount = 0;

 

int motor1pin1 = 22; 
int motor1pin2 = 23; 
int motor1pwm = 2;


int motor2pin1 = 24; 
int motor2pin2 = 25; 
int motor2pwm = 3;







void setup () 
{

    pinMode(motor1pin1, OUTPUT);

    pinMode(motor1pin2, OUTPUT);
  
    pinMode(motor1pwm, OUTPUT);


    pinMode(motor2pin1, OUTPUT);

    pinMode(motor2pin2, OUTPUT);
  
    pinMode(motor2pwm, OUTPUT);


    Serial.begin(9600);

}

 

 

void loop() 
{
  
    while (cyclecount<repeatcycle) {

 

    cyclecount = cyclecount+1;

 

 
    analogWrite(motor1pwm, motor1speed);
  
    digitalWrite(motor1pin1, HIGH);
  
    digitalWrite(motor1pin2, LOW);



    delay(motor1duration);

    digitalWrite(motor1pin1, LOW);
    digitalWrite(motor1pin2, LOW);


    delay(pause1);


  
    analogWrite(motor2pwm, pump2speed);
  
    digitalWrite(motor2pin1, HIGH);
  
    digitalWrite(motor2pin2, LOW);



    delay(motor2duration);

    digitalWrite(motor2pin1, LOW);
    digitalWrite(motor2pin2, LOW);


    delay(pause2);

}
 
}

IMO the processing firmware is missing from your Arduino code.
