“FanisActive cannot be resolved to a variable”
Here the brackets are wrong. They must enclose the code section that you want to be executed when the if condition is true
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 ().
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 {
}
}
How can I define variable before setup()?
Should I use String?
??
How do you switch your fan on and off now?
Does this work already?
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?
No, please use boolean
I can create ellipse and add fill. I need to define variable. Could you rewrite me for define variable?
Okay! What I should write?
boolean fanIsActive=false;
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;
}

Thankssssss You are awesomeee
Can we do for one button? If fan is active, button is green. If fan is inactive, button is red…
You know codes. How can we do it?
Yes, we can.
This stays the same.
if (fanIsActive)
fill(255, 0, 0);
else
fill(0, 245, 0);
ellipse(1870, 974, 15, 15);
Kill one button, the upper one of the two.
The remaining button is something like:
if (mouseX >= buttonJ_x && mouseX <= buttonJ_x + buttonJ_width &&
mouseY >= buttonJ_y && mouseY <= buttonJ_y + buttonJ_height) {
// toggle
if(fanIsActive) {
// it's active, we want to deactivate
buttonJ_clicked = true;
fill(0, 255, 0);
ellipse(1870, 974, 15, 15);
fanIsActive=false; // !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
myStepMotor.write("9");
}
else
{
// it's NOT active, we want to activate
buttonJ_clicked = true;
fill(0, 255, 0);
ellipse(1870, 974, 15, 15);
fanIsActive=true; // !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
myStepMotor.write("8"); // !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
}
} else {

}
Thanks, I will try it
