Day 4

For homework i had to create an RGB LED that changes color depending on what button is pressed here is my code

const int BLED=9; //Blue LED on Pin 9
const int GLED=10; //Green LED on Pin 10
const int RLED=11; //Red LED on Pin 11
const int BUTTON=2; //The Button is connected to pin 2
const int XBUTTON=3;
const int YBUTTON=5;
boolean lastButton = LOW; //Last Button State
boolean currentButton = LOW; //Current Button State
boolean XlastButton=LOW;
boolean XcurrentButton=LOW;
boolean YlastButton=LOW;
boolean YcurrentButton=LOW;
int ledMode = 0; //Cycle between LED states
int XledMode=0;
int YledMode=0;





void setup()
{
 pinMode (BLED, OUTPUT); //Set Blue LED as Output
 pinMode (GLED, OUTPUT); //Set Green LED as Output
 pinMode (RLED, OUTPUT); //Set Red LED as Output
 pinMode (BUTTON, INPUT); //Set button as input (not required)
 pinMode (XBUTTON, INPUT);
 pinMode (YBUTTON, INPUT);

}



boolean debounce(boolean last)
{
 boolean current = digitalRead(BUTTON); //Read the button state
 if (last != current) //if it's different...
 {
 delay(5); //wait 5ms
 current = digitalRead(BUTTON); //read it again
 }
 return current; //return the current value
}




boolean Xdebounce(boolean Xlast)
{
  boolean Xcurrent=digitalRead(XBUTTON);
    if ( Xlast!= Xcurrent)
    {
      delay(5);
      Xcurrent=digitalRead(XBUTTON);
    }

  return Xcurrent;
}




boolean Ydebounce(boolean Ylast)
{
 boolean Ycurrent = digitalRead(YBUTTON); //Read the button state
 if (Ylast != Ycurrent) //if it's different...
 {
 delay(5); //wait 5ms
 Ycurrent = digitalRead(YBUTTON); //read it again
 }
 return Ycurrent; //return the current value

}


/*
* LED Mode Selection Pass a number for the LED state and set it accordingly.
*/
void setMode(int mode)
{
 //RED
   switch (mode)
    {
        case 1:
      digitalWrite(RLED, HIGH);

}

 {

for (int i=100; i<=400; i=i+100)
   {
