3 switches, code for each switch, trouble figuring out how to read each switch..

I'm not sure it is the case of them being turned on/off quickly when they turn on like they are supposed to

It is, I can see it in the logic.

if(currentMillis - previousMillis > ledFOn){

digitalWrite(ledFPin, HIGH);
   }
   ...
  if(currentMillis - previousMillis > ledAOn){
    digitalWrite (ledBPin, LOW);
    digitalWrite (ledAPin, LOW);
    digitalWrite(ledCPin, LOW);
    digitalWrite(ledDPin, LOW);
    digitalWrite(ledEPin, LOW);
    digitalWrite(ledFPin, LOW);
}




If these two if statements fire in the same loop iteration, there will be rapid on/offs. Plug in the value of 2.3 seconds (for current minus previous) and tell me if they both will fire.

Woo Hoo!!!

I got it to work the way I want it to. If someone could check the code to see if you see any issues? I will then be working on the button code probably tomorrow. Here is the code that works:

// test code utilizing blink without delay.
// written 11/13/12.

const int ledAPin = 7;      // the number of the LED pin
const int ledBPin = 8;      // the number of the 2nd LED pin
const int ledCPin = 9;      // the number of the 3rd LED pin
const int ledDPin = 10;     // the number of the 4th LED pin
const int ledEPin = 11;     // the number of the 5th LED pin
const int ledFPin = 12;     // the number of the 6th LED pin

// Variables will change:

long previousMillis = 0;        // will store last time LED was updated


long ledAOn = 2500;           // total time ledA is on
long ledBOn = 300;              // the time ledB will come on
long ledBOff = 1700;            // the time ledB goes off
long ledCOn = 600;
long ledCOff = 1400;
long ledDOn = 900;
long ledDOff = 1100;
long ledEOn = 1200;
long ledEOff = 800;
long ledFOn = 1500;
long ledFOff = 500;
long totalTime = 3000;          // the total time for the sequence


void setup() {
  // set the digital pin as output:
  pinMode(ledAPin, OUTPUT);      
  pinMode(ledBPin, OUTPUT);
  pinMode(ledCPin, OUTPUT);
  pinMode(ledDPin, OUTPUT);
  pinMode(ledEPin, OUTPUT);
  pinMode(ledFPin, OUTPUT);
}

void loop()
{

  unsigned long currentMillis = millis();
 
//  if(currentMillis - previousMillis > interval) {
//    // save the last time you blinked the LED 
//    previousMillis = currentMillis;   
//
//    // if the LED is off turn it on and vice-versa:
//    if (ledState == LOW)
//      ledState = HIGH;
//    else
//      ledState = LOW;
//
//    // set the LED with the ledState of the variable:
//    digitalWrite(ledPin, ledState);

    if(currentMillis - previousMillis > totalTime) {
      previousMillis = currentMillis;
    }

    if(currentMillis - previousMillis > ledFOn){
      if(currentMillis - previousMillis < ledAOn)
      digitalWrite(ledFPin, HIGH);
    }

    if(currentMillis - previousMillis > ledEOn){
      if(currentMillis - previousMillis < ledAOn)
      digitalWrite(ledEPin, HIGH);
    }

    if(currentMillis - previousMillis > ledDOn){
      if(currentMillis - previousMillis < ledAOn)
      digitalWrite(ledDPin, HIGH);
    }

    if(currentMillis - previousMillis > ledCOn){
      if(currentMillis - previousMillis < ledAOn)
      digitalWrite(ledCPin, HIGH);
    }
      
    if(currentMillis - previousMillis > ledBOn){
      if(currentMillis - previousMillis < ledAOn)
        digitalWrite(ledBPin, HIGH);
    }

    if(currentMillis - previousMillis < ledAOn){
      digitalWrite (ledAPin, HIGH);
    }
    
    if(currentMillis - previousMillis > ledAOn){
     digitalWrite (ledBPin, LOW);
     digitalWrite (ledAPin, LOW);
     digitalWrite(ledCPin, LOW);
     digitalWrite(ledDPin, LOW);
     digitalWrite(ledEPin, LOW);
     digitalWrite(ledFPin, LOW);
}
 
   if(currentMillis - previousMillis > totalTime) {
     previousMillis = currentMillis;
  }
}

Awesome....thanks again.
