For Button3, Pin13, I'd like to press that button, have the light stay off for 180 seconds, turn on for 10 seconds, and then turn back off, and do the same thing every time I press that button.
This implies the LED 13 is ON before you push the button3.

I really appreciate all your hard work! Thank you so much! It works great! I was thinking about getting a buzzer to play a horn kind of sound when either of the LEDs are lit up. Can I safely assume I could do this with a cheap passive buzzer? Thanks again! By the way here is the code in case someone else would like to use it:
//+5 turns LED on
#define LEDon HIGH
#define LEDoff LOW
//+5 turns LED off
//#define LEDon LOW
//#define LEDoff HIGH

I actually just tried it out for the full three minutes and I realize that must be why it was not working just right. I thought it was odd that the three minute timer was going off about 15 seconds early even though the short timer seemed to be working fine. Pressing either button starts the timer for Pin13. How can I fix this, so each timer is totally independent of each other? Thank you again!
I think you need to change it to look like this, but I have not tried:
// read the state of the push button value:
buttonState = digitalRead(buttonPin2);
//if button pressed start timing LED sequence
if (flag12 == false && buttonState == HIGH)
{
//enable timing
flag12 = true;
Millis12 = millis();
//LED on
digitalWrite(ledPin12, HIGH);
}
// read the state of the push button value
buttonState = digitalRead(buttonPin3);
//if enabled and button pressed start LED timing sequence
if (flag13 == false && buttonState == HIGH)
{
//enable timing
flag13 = true;
myState = 0;
Millis13 = millis();
MyTime13 = 180*1000UL; //LED OFF for 180 seconds
digitalWrite(ledPin13, LEDoff);
//LED will remain OFF for 180 more seconds before it comes ON for 10 sec
}
etc.
I switched it up like that, and button 2 seems to have to be pressed up for button 3 to work. I shortened the time for button 3 to activate led 13 from 180 to 5 seconds to help test it easier. Here is that updated code. I'm not sure why it seems like the two buttons are still related.

My push button is from a remote where the receiver is on my breadboard. I made a quick layout in a program. I think this is pretty much how my buttons and LEDs are wired. Are there any problems? Thanks!
LarryD:
This implies the LED 13 is ON before you push the button3.
Is this correct?
How is your LED wired?
Thank you for that info. And, sorry I did not answer this question. LED 13 would be OFF before I push button3. Is that why it hasn't been doing what I'd like it to do since I took both of your codes and put them together?
Thank you! Ahh this was driving me crazy but now I believe it is all good. I'd give you more karma points on here if I could. You are a terrific person!
I believe I understand the principles of a good part of the code. I read about boolean a little bit and that is one of the more confusing aspects as I'm still pretty lost as to what exactly that can do.
If you make a variable a boolean, you can examine it with an if statement.
It has two possible states. true/false
boolean timerEnabled = false; // 'type' = boolean apply it to variable timerEnabled, set it to false.
'false' and 'true' are understood by the compiler.
==================================
boolean enabledTimer = false;
.
.
.
// ask if the variable is currently equal to 'true'. You could also use timerEnabled == false.
if(timerEnabled == true)
{
//if it is equal, then you do some stuff here
}
==================================
You could have said:
byte enabledTimer = 0; // a byte can be anything from 0 to 255
.
.
.
if(timerEnabled == 1) //asks if the variable is currently equal to 1
{
//if it is equal, then you do some stuff
}
==================================
You could have said:
int enabledTimer = 1234; // an int can be from -32,768 to 32,767
.
.
.
if(timerEnabled == 1234) //asks if the variable is currently equal to 1234
{
//if it is equal, then you do some stuff
}
