I added Buttons for Fan On/Off on Processing

Processing Electronics (Arduino, etc.)
1

Hello everyone,
I created Step Motor and Led System with Arduino and Processing. I added a Fan on my system. I added Buttons for Fan On/Off on Processing. I added Status. I want to this. If Fan is Active, Button will be green. If Fan is Inactive, Button will be red. I did something but didn’t be my want like. You have to see photo for understand me. I will share photo and codes under the topic…

Before fill insert an

if( FanIsInactive )
     fill(....
     else fill(.....

And use your appropriate variable name

So the entire structure:

if(buttonA_clicked){ 

   if( FanisInactive )
        fill(....
        else fill(.....

} else

Thank you for reading and returning.
I did your say. It give me Error. Where I did wrong? Could you rewrite for me??

  if (mouseX >= buttonJ_x && mouseX <= buttonJ_x + buttonJ_width && 
    mouseY >= buttonJ_y && mouseY <= buttonJ_y + buttonJ_height) {
    if (buttonJ_clicked) {
      if ( FanisInactive );
      fill(0, 255, 0);
      ellipse(1870, 974, 15, 15);
    } else {
      fill(255, 0, 0);
      ellipse(1870, 974, 15, 15);
      myStepMotor.write("9");
      print("9");
    } else {
      buttonI_clicked = false;
    }
  }
}
4

no semicolon ; at this place!!

It ends the condition!!

Use ctrl-t for auto-indents to spot those cases

Also you need a {

Please check the { } using ctrl-t

5

Where is the wrong?

  if (mouseX >= buttonD_x && mouseX <= buttonD_x + buttonD_width && 
    mouseY >= buttonD_y && mouseY <= buttonD_y + buttonD_height) {
    if (buttonD_clicked) {
      if ( FanisActive ) {
      }
      fill(255, 0, 0);
      ellipse(280, 535, 15, 15);
      myStepMotor.write("3");
      print("3");
    } else {
      buttonD_clicked = false;
    }
  }
6

“FanisActive cannot be resolved to a variable”

7

Here the brackets are wrong. They must enclose the code section that you want to be executed when the if condition is true

8

I made this name up.

Do you already have a variable that indicates whether the fan is active? Then use it here.

Otherwise you should declare the variable before setup ().

9

Could you rewrite for me just this part

  if (mouseX >= buttonD_x && mouseX <= buttonD_x + buttonD_width && 
    mouseY >= buttonD_y && mouseY <= buttonD_y + buttonD_height) {
    if (buttonD_clicked) {
      if ( FanActive ) {
      }
      fill(255, 0, 0);
      ellipse(280, 535, 15, 15);
      myStepMotor.write("3");
      print("3");
    } else {
    }
  }
10

How can I define variable before setup()?

11

Should I use String?

12

??

How do you switch your fan on and off now?

Does this work already?

13

Okay! Okay! 1 minutes. I use led. This is easy. I must define to use variable. I can define variable with int. Am I right?

14

No, please use boolean

15

I can create ellipse and add fill. I need to define variable. Could you rewrite me for define variable?

16

Okay! What I should write?

17

boolean fanIsActive=false;

18

OKay, I got it working now

at the end of draw you are drawing the ellipses

you want to change these, right?

Do this


  if (fanIsActive)
    fill(2, 255, 0);
  else 
  fill(255, 0, 2);
  ellipse(1870, 889, 15, 15);

  if (fanIsActive)
    fill(255, 0, 0);
  else 
  fill(0, 245, 0);  
  ellipse(1870, 974, 15, 15);

Before setup say boolean…

AND

at the very end of your sketch where you check buttonI and J say (see !!!)

 if (mouseX >= buttonI_x && mouseX <= buttonI_x + buttonI_width && 
    mouseY >= buttonI_y && mouseY <= buttonI_y + buttonI_height) {
    buttonI_clicked = true;
    fill(0, 255, 0);
    ellipse(1870, 889, 15, 15);
    myStepMotor.write("8");
    fanIsActive=true;   // !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
    print("8");
  } else {
    buttonI_clicked = false;
  }
  if (mouseX >= buttonJ_x && mouseX <= buttonJ_x + buttonJ_width && 
    mouseY >= buttonJ_y && mouseY <= buttonJ_y + buttonJ_height) {
    buttonJ_clicked = true;
    fill(0, 255, 0);
    ellipse(1870, 974, 15, 15);
    fanIsActive=false;   // !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
    myStepMotor.write("9");
  } else {
    buttonJ_clicked = false;
  }
