PUSH BUTTONS

  Use pushbuttons for ditants for the pin numbers.
// This will make it easier to follow the code below.

 // pushbutton pin
 const int buttonPin = 3;

 //RGB LED pins
 const int redPin = 11;    
 const int greenPin = 10;
 const int bluePin = 9;


//create a variable to store a counter and set it to 0
int counter = 0;
void setup()
{
  // Set up the pushbutton pins to be an input:
  pinMode(buttonPin, INPUT);

  // Set up the RGB pins to be an outputs:
  pinMode(redPin, OUTPUT);  
  pinMode(greenPin,OUTPUT);
  pinMode(bluePin,OUTPUT);
}


void loop()
{
 // local variable to hold the pushbutton states
  int buttonState;  

  //read the digital state of buttonPin with digitalRead() function and store the           //value in buttonState variable
  buttonState = digitalRead(buttonPin);

  //if the button is pressed increment counter and wait a tiny bit to give us some          //time to release the button
  if (buttonState == LOW) // light the LED
  {
    counter++;
    delay(150);
  }

  //use the if satement to check the value of counter. If counter is equal to 0 all         //pins are off
  if(counter == 0)
  {
   digitalWrite(redPin,LOW);
   digitalWrite(greenPin,LOW);
   digitalWrite(bluePin,LOW);
  }

  //else if counter is equal to 1, redPin is HIGH
  else if(counter == 1)
  {
   digitalWrite(redPin,HIGH);
   digitalWrite(greenPin,LOW);
   digitalWrite(bluePin,LOW);
  }

  //else if counter is equal to 2 greenPin is HIGH
  else if(counter ==2)
  {
   digitalWrite(redPin,LOW);
   digitalWrite(greenPin,HIGH);
   digitalWrite(bluePin,LOW);
  }

  //else if counter is equal to 3 bluePin is HIGH
  else if(counter ==3)
  {
   digitalWrite(redPin,LOW);
   digitalWrite(greenPin,LOW);
   digitalWrite(bluePin,HIGH);
  }

  //else reset the counter to 0 (which turns all pins off)
  else
  {
   counter =0;
  }
}
