Code Description

  • Pre-set color: " color_m[9][3"; Currently, there are nine colors, which can be changed by users. The number of color needs to correspond to array. For example, if you add two colors, they needs to changed to " color_m[11][3]" correspondingly.
  • Definition of the Joystick control pin: 
#define JoystickX_PIN A1
#define JoystickY_PIN A0
  • Color selection in the X-axis direction
	  if (sensorValueY <= 10)
  {
    delay(500);
    num++;
    if (num > 8)
      num = 0;
  }
  else if (sensorValueY > 800)
  {
    delay(500);
    num--;
    if (num < 0)
      num = 8;
  }
  • Brightness selection in the Y-axis direction. 
if (sensorValueX <= 10)
  {
    delay(10);
    color_l++;
    if (color_l > 255)
      color_l = 255;
  }
  else if (sensorValueX > 800)
  {
    delay(10);
    color_l--;
    if (color_l < 0)
      color_l = 0;
  }
  • Colored LED display
colorWipe(strip.Color(map(color_l, val_min, val_max, 0, color_m[num][0]), map(color_l, val_min, val_max, 0, color_m[num][1]), map(color_l, val_min, val_max, 0, color_m[num][2])));

Result

Toggle the Joystick in the X-axis direction to choose color of the LED light and in the Y-axis to select brightness.
