using either a rotory encoder or button press count to change pwm mode

The initial example I wrote used seven pins but you only need 5 (my bad), just changed the 7 to a 5 in the initial pin table and any for/next loops that use it. Hopefully this will work and compile fine.

// List of input pins to read
const int Input_Pins [5] = {
    3,4,5,6,7};

void setup(){
    // set list of pins to input
    for (int a=0;a<5;a++){
        pinMode(Input_Pins[a],INPUT);
    }
}

void loop(){ 
    // Read the pins
    int x = readPins();

    // Act on returned value
    switch (x) {
    case 3:     // Off
        // statements
        break;
    case 1:    // Hi
        // statements
        break;
    case 2:   // Med
        // statements
        break;
    case 16:   // Low
        // statements
        break;
     case 19:   // Strobe
        // statements
        break;
    default:    // Any other value, do nothing
        // statements
        break;
    }
}

int readPins(){

    int result = 0;    // Setup result register

    for (int a=0;a<5;a++){    // Index through array
        int x=digitalRead(Input_Pins[a]);    // Read pin state
        result=result << 1;    // Rotate result register
        result = result | x;    // OR pinstate into bit 0
    }
    return result;    // Return 
}
