==Hardware Buildup==
* Setup 1：Connect CoreUSB to the computer, open program example, then select the right board and download program via serial port.

==Software Debugging==
Code Description 
* Color pre-set: " color_m[9][3]" (With nine kinds of color and users can change according to personal needs.)
*Joystick controls pin description:
<source lang="cpp">
#define JoystickX_PIN A1
#define JoystickY_PIN A0
</source>
*Select color on the X-axis 
 <source lang="cpp">
	  if (sensorValueY <= 10)
  {
    delay(500);
    num++;
    if (num > 8)
      num = 0;
  }
  else if (sensorValueY > 800)
  {
    delay(500);
    num--;
    if (num < 0)
      num = 8;
  }
</source>
*Select brightness on the Y-axis.
 <source lang="cpp">
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;
  }
</source>
*Light display 
<source lang="cpp">
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])));
</source>

==Result==
Choose color on the X-axis and brightness on the Y-axis. You can also build a beautiful shell with LEGO.
