Problem with writing code for Light project.

Projects General Guidance

Dear forum members.

My name is Bas de Boer. Love using arduino and making projects with it. Only this time i have a little problem with the code.

I'm making analog RGB strips light to my bedroom. And i want to use 2 rotary encoders and 2 switches for 2 RGB strips. One encoder and switch for one strip

The project is like this;

With the encoders i wan't select the colors of the RGB led strips. One encoder and one switch ( to make color swirl ) vor each strip.

I have problems with making the code. I have a piece of code that works with one encoder and no color swirl.
( The code for 1 rotary encoder );

// RGB bedroom

int redPin = 3;
int greenPin = 5;
int bluePin = 6;
int aPin = 4;
int bPin = 7;
int buttonPin = 2;

boolean isOn = true;
int color = 0;
// color libary
long colors[48]= {
  0xFF2000, 0xFF4000, 0xFF6000, 0xFF8000, 0xFFA000, 0xFFC000, 0xFFE000, 0xFFFF00, 
  0xE0FF00, 0xC0FF00, 0xA0FF00, 0x80FF00, 0x60FF00, 0x40FF00, 0x20FF00, 0x00FF00,
  0x00FF20, 0x00FF40, 0x00FF60, 0x00FF80, 0x00FFA0, 0x00FFC0, 0x00FFE0, 0x00FFFF,
  0x00E0FF, 0x00C0FF, 0x00A0FF, 0x0080FF, 0x0060FF, 0x0040FF, 0x0020FF, 0x0000FF,
  0x2000FF, 0x4000FF, 0x6000FF, 0x8000FF, 0xA000FF, 0xC000FF, 0xE000FF, 0xFF00FF,
  0xFF00E0, 0xFF00C0, 0xFF00A0, 0xFF0080, 0xFF0060, 0xFF0040, 0xFF0020, 0xFF0000
};

void setup()
{
  pinMode(aPin, INPUT);
  pinMode(bPin, INPUT);
  pinMode(buttonPin, INPUT);
  pinMode(redPin, OUTPUT);
  pinMode(greenPin, OUTPUT);
  pinMode(bluePin, OUTPUT);
}

void loop()
{
  if (digitalRead(buttonPin))
  {
    isOn = ! isOn;
    delay(200);    // de-bounce
  }
  if (isOn)
  {
    int change = getEncoderTurn();
    color = color + change;
    if (color < 0)
    {
      color = 47; 
    }
    else if (color > 47)
    {
      color = 0;
    }
    setColor(colors[color]);
  }
  else
  {
   setColor(0); 
  }
  delay(1);
}

int getEncoderTurn()
{
  // return -1, 0, or +1
  static int oldA = LOW;
  static int oldB = LOW;
  int result = 0;
  int newA = digitalRead(aPin);
  int newB = digitalRead(bPin);
  if (newA != oldA || newB != oldB)
  {
    // something has changed
    if (oldA == LOW && newA == HIGH)
    {
      result = -(oldB * 2 - 1);
    }
  }
  oldA = newA;
  oldB = newB;
  return result;
} 

void setColor(long rgb)
{
  int red = rgb >> 16;
  int green = (rgb >> 8 ) & 0xFF;
  int blue = rgb & 0xFF; 
  analogWrite(redPin, 255 - red);
  analogWrite(greenPin, 255 - green);
  analogWrite(bluePin, 255 - blue);
}

My question is to you ( the forrums users ). Would you help me with this code to make it use 2 encoders for 2 strips and 2 buttons for 2 color swirl on the led strips

Any help appreciated. Thanks.

The AdaEncoder library would help out with the encoders. That appears to be your primary problem?

Thank you for your post.

The problem is that i want to program it so that i can use 2 analoge RGB strips with 2 encoders and 2 butons ( 1 encoder and button for each strip ). The button for color swirl.
