Edit:
New Plea:
If anyone else knows how to do this, please chime in. I am sure there is one man or woman in the world (at least!) who has used a toggle switch to switch between two program loops (that only execute once at the time of the state change). I will try to simplify my goals as much as possible to make a solution easy to achieve.
Mode 1 - Switched ON
execute playcomplete();
digitalWrite(LED, HIGH);
wait until mode 2 activated
x1
Mode 2 - Switched OFF
execute playcomplete();
digitalWrite(LED, LOW);
wait until mode 1 activated
x1
Variable Progression
PIN - HIGH; VAR - LOW (State 1)
Mode 1 Init
PIN - HIGH; VAR - HIGH (Middle State, nothing happens)
While Mode 1
PIN - LOW; VAR - HIGH (State 2)
Mode 2 Init
PIN - LOW; VAR - LOW (Middle State, nothing happens)
While Mode 2
Here is what I have thus far:
int buttonState = LOW;
int newbuttonState = HIGH;
void setup() {
pinMode(6, INPUT);
pinMode(7, OUTPUT);
void loop() {
buttonState = digitalRead(6); // Checks the switch for it's current position
if (buttonState == HIGH && newbuttonState == LOW) { // Requires switch to be ON, and it's previous position to be OFF.
digitalWrite(7, HIGH); // LED on
playcomplete("act.wav"); // Play .WAV file
newbuttonState = HIGH; // Sets the variable into it's ON position
}
else if (buttonState == LOW && newbuttonState== HIGH) { // Requires switch to be off, and it's previous position to be ON.
digitalWrite(7, LOW); // LED off
playcomplete("deact.wav"); // Play .Wav file
newbuttonState = LOW; // Sets the variable into it's OFF position
}
}
Please feel free to edit and add to my code and repaste up here. This is driving me nuts as It's so simple and I need to get past it to progress with my project. :c Please... pleasee cry for help
Anyone brilliant around here?

Greetings,
I dearly hope this is in the right section... I have searched these forums and the google several times and due to my silly distraught mind can not find the solution to my problem...
I am attempting to use a toggle switch to engage one of two modes. When the switch is turned on, mode 1 is engaged and an led turns on complimented by an activation message (wave shield). When the switch is turned off, mode 2 is engaged and an led turns off comp'd by a deactivation message.
I am sure this is truly a simple thing, but for the life of me I am stuck and in dire need of support.
Here is my current sketch, as you may immediately notice, I am either caught in a constant loop of block 1 and block 2, or only block 2, depending on the switch state.
Pleaseth helpeth me,
