flip_flop_with_3inputs_loop.ino

/*
  Adjust our flip-flop, so that when pin 8, 7 or 6 is HIGH
  the flashing is faster and when pin 8, 7 or 6 LOW it's slower
  Added loops to reduce repetitive code

// Pin 13 has an LED connected on most Arduino boards.
// give it a name:
int led = 13;
int newled = 5;         // add our second LED on pin 5
int time_delay = 500;   // set time delay (mS) duration here
int input_value = 1;    // set our initial input value

// the setup routine runs once when you press reset:
void setup() {                
  // initialize the digital pin as an output.
  pinMode(led, OUTPUT);
  pinMode(newled, OUTPUT);    // set up our second LED as output
  for (int thisPin = 6; thisPin < 9; thisPin++) {
     pinMode(thisPin, INPUT); // set pins 6-8 as inputs
  }
}

// the loop routine runs over and over again forever:
void loop() {
  time_delay = 1000;             // set delay to 1000 ms
  // loop through pins starting at 6 and stopping at 8
  for (int thisPin = 6; thisPin < 9; thisPin++) { 
     input_value = digitalRead(thisPin);  // read input pin
     if (input_value == 1) {              // if it's HIGH
        time_delay /= 2;                  // set delay to half
     }   
  }
  digitalWrite(led, HIGH);    // turn LED ON (HIGH is the voltage level)
  digitalWrite(newled, LOW);  // turn newLED OFF (LOW is the voltage level)
  delay(time_delay);          // wait for time_delay
  digitalWrite(led, LOW);     // turn LED OFF by making the voltage LOW
  digitalWrite(newled, HIGH); // turn LED ON by making the voltage HIGH
  delay(time_delay);          // wait for time_delay
