==Document==
Android Client: 
Caution: The new BT 4.0 version can only be supported by Android 4.3 and higher. Here we offer Android App. 

APP download：'''[[File:Microduino-LAMP-APP.zip]]''

==Hardware Buildup==
*Setup 1：Stack CoreUSB, BT and Sensorhub. 
[[File:CoreUSB_Ble_Sensorhub.jpg|600px|center|thumb]]
*Setup 2：Connect the lantern to the A0 pin of Sensorhub.

==Software Debugging==
*Setup 1：Build IDE, connect CoreUSB to your PC and download program code. 
[https://github.com/Microduino/Microduino_Tutorials/blob/master/MCookie_Tutorial/ble_color_led/ble_color_led.ino ble_color_led]
*Setup 2：Download Android Client, decompress, install and open it. Make sure that is operated with Bluetooth open.  
[[File:Microduino_BT_Serial_1.png||300px|center|thumb]]
*Setup 3：Click SCAN on top right, name it Microduino and click connection. 
[[File:Microduino_BT_Serial_2.png||300px|center|thumb]]
*Setup 4：It appears Serial Present on top right during initializing and then turn to Serial Ready, meaning normal communication.

*APP description:
**If you have multiple colored lights, you can switch to Multi Colore mode. The maximum is six. 
**Control the brightness through the circular ring. 
**Switch to turn on or off through the bottom button.

*Code description: One part for receiving Bluetooth information and the other for controlling color combination of the light via analog value.
**Reading Bluetooth information
The use of BT serial port is baseed on the selection of serial jumper on the board. The default serial port is 0：Serial.
<source lang="cpp">
#define my_Serial Serial
</source>

<source lang="cpp">
void ble()
{
  while (my_Serial.available())
  {
    char c = my_Serial.read();
    delay(2);

    if (c == 'C')
      buffer_sta = true;
    if (c == '\n')
    {
      color_en = true;
      safe_ms = millis();
    }
    if (buffer_sta)
    {
      buffer[buffer_num] = c;
      buffer_num++;
    }
    //  Serial.println(c);
    //Serial.println(color_en);
  }

  if (buffer_sta)
  {
    buffer_sta = false;

    sscanf((char *)strstr((char *)buffer, "C:"), "C:%d,%d,%d,%d", &sta[0], &sta[1], &sta[2], &sta[3]);

    for (int a = 0; a < buffer_num; a++)
      buffer[a] = NULL;
    buffer_num = 0;

    for (int i = 0; i < 4; i++)
    {
      Serial.print(sta[i]);
      Serial.print(",");
    }
    Serial.println(" ");

    if (-1 == sta[3]) {
      colorSet(strip.Color(sta[0], sta[1], sta[2]));
    }
    else if ((0 <= sta[3]) && (sta[3] < PIXEL_COUNT)) {
      colorSet(strip.Color(sta[0], sta[1], sta[2]), sta[3]);
    }
  }

  if (millis() - safe_ms > 3000)
  {
    safe_ms = millis();
    color_en = false;
  }
}
</source>
**Color change of the light. 
When there is Bluetooth connection, the color is: 
<source lang="cpp">
     if (-1 == sta[3]) {
      colorSet(strip.Color(sta[0], sta[1], sta[2]));
    }
    else if ((0 <= sta[3]) && (sta[3] < PIXEL_COUNT)) {
      colorSet(strip.Color(sta[0], sta[1], sta[2]), sta[3]);
    }
</source>
Otherwise, it will control color automatically. 
<source lang="cpp">
  if (!color_en)
  {
    rainbowCycle(10, 255, 0, 0, 0);
    rainbowCycle(10, 255, 0, 0, 1);

    rainbowCycle(10, 0, 255, 0, 0);
    rainbowCycle(10, 0, 255, 0, 1);

    rainbowCycle(10, 0, 0, 255, 0);
    rainbowCycle(10, 0, 0, 255, 1);

    rainbowCycle(10, 255, 0, 225, 0);
    rainbowCycle(10, 255, 0, 225, 1);

    rainbowCycle(10, 247, 139, 5, 0);
    rainbowCycle(10, 247, 139, 5, 1);

    rainbowCycle(10, 255, 255, 0, 0);
    rainbowCycle(10, 255, 255, 0, 1);

    rainbowCycle(10, 0, 255, 255, 0);
    rainbowCycle(10, 0, 255, 255, 1);

    for (int i = 0; i < 3; i++)
      rainbow(30);
  }
</source>

==Result==
By Microduino, you can control colored lights through your phone and get any color you want. (You can build a beautiful frame with LEGO. )
