When button clicked, let something move

Ditger

So i build something so that when you push a button, an LED is going to light up

Now the issue that I'm having is that when i click the button, it doesn't do anything

this is my code in processing

import processing.serial.*;
import cc.arduino.*;

Arduino arduino;
int BUTTON1 = 11;
int BUTTON2 = 10;
int BUTTON3 = 9;
int BUTTON4 = 8; 


void setup() 
{
  size(600, 600);
arduino = new Arduino(this, Arduino.list()[0], 57600);


}

void draw()
{   
  int x = 150;
  int y = 150;
  ellipse(x,y,50,50);
   if(arduino.digitalRead(BUTTON1) == Arduino.HIGH) {
     x = x + 50;
   }
}

I hope that someon can help me

Please edit your post (gear icon in the top right corner of your post), select your code and hit ctrl+o to format your code. Make sure there is an empty line above and below your code.

When you were turning the LED, were you doing it from Processing?

I edited the post, the LED does turn on because i've programmed that in Arduino, but the ellipse in processing doesn't move

Can you post your ino code?

  const int LED1 = 5;
  const int BUTTON1 = 11;

  const int LED2 = 3;
  const int BUTTON2 = 10;

  const int LED3 = 2;
  const int BUTTON3 = 9;

  const int LED4 = 4;
  const int BUTTON4 = 8;

  void setup(){
    Serial.begin(9600);
    pinMode(LED1,OUTPUT);
    pinMode(BUTTON1,INPUT);
    pinMode(LED2,OUTPUT);
    pinMode(BUTTON2,INPUT);
    pinMode(LED3,OUTPUT);
    pinMode(BUTTON3,INPUT);
    pinMode(LED4,OUTPUT);
    pinMode(BUTTON4,INPUT);
  }

  void loop(){
    if(digitalRead(BUTTON1) == HIGH){
      Serial.println("Button 1 has been pressed");
      digitalWrite(LED1,HIGH);
    }else{
      digitalWrite(LED1,LOW);
    }

    if(digitalRead(BUTTON2) == HIGH){
       Serial.println("Button 2 has been pressed");
       digitalWrite(LED2,HIGH);
    }else{
        digitalWrite(LED2,LOW);
    }

    if(digitalRead(BUTTON3) == HIGH){
      Serial.println("Button 3 has been pressed");
      digitalWrite(LED3,HIGH);
    }else{
      digitalWrite(LED3,LOW);
    }

    if(digitalRead(BUTTON4) == HIGH){
      Serial.println("Button 4 has been pressed");
      digitalWrite(LED4,HIGH);
    }else{
      digitalWrite(LED4,LOW);
    }            
  }

Is this your first sketch interacting with an arduino unit or have you done it before?

Are you using firmata? If so, this post could help: https://forum.processing.org/two/discussion/20955/arduino-not-being-reset-when-running-a-processing-sketch/p1
AND https://adestefawp.wordpress.com/learning/using-arduino-firmata-and-processing-together/

Otherwise, you could use the following examples, reading the bytes directly from the serial port. Remark: If you loaded the firmata code into your arduino, you should stick to the above comment.

I do use firmata, and still it doesn't move when i click BUTTON1

So my understanding is that if you use firmata, then you should be interacting with your arduino exclusively from Processing. I don't understand how you can be changing the LED from your arduino code if you have loaded the firmata in your arduino device.

I suggest following the firmata example provided in the previous post: https://adestefawp.wordpress.com/learning/using-arduino-firmata-and-processing-together/
