==Objective==
Speak toward MIC, the lamp will change along with the sound rhythm.

==principle==
*MIC sensor introduction 
MIC sensor can turn sound signal to electricity signal. 
It can detect sound volume but can't detect certain sound. 
*Rhythm Lamp 													
Detect sound volume via MIC sensor and the system will judge which color range the sound belongs to. At the same, comparing with the pre-set trigger value and choosing to open or close light change, therefore, to control color change of the lamp.

==Preparation==
*Setup 1：Connect CoreUSB and PC/Mac with USB cable and open Arduino IDE.
[[File:CoreUSB_Ble_pc.jpg|600px|center]]
*Setup 2：Download program:[https://github.com/Microduino/Microduino_Tutorials/blob/master/MCookie_Tutorial/SHENGRI/SHENGRI.ino SHENGRI]
[[File: _SHENGR.jpg|600px|center]]

* Setup 3：Load code, copy program to IDE. Select the right boardcard and COM port and then download after passing the compiling.  
==Program Description==
*Read sound analog value (A0 pin), which can be defined by users. Then, print analog sound data via serial port monitor. 
<source lang="cpp">
  int v=analogRead(A0);
  Serial.println(v);
</source>
*Detect sound volume every 100ms and distinguish the sound. Soudn range is defined in " zone_vol[3]", which is among 100-600. Users can change that according to personal needs. 
<source lang="cpp">
  if(millis()-timer[0]>100)
  {
    timer[0]=millis();
    if(v>zone_vol[0])
      zone=0;//Red 
    else if(v>zone_vol[1])
      zone=1;//Green 
    else if(v>zone_vol[2])
      zone=2;//Blue
    else
      zone=9;
  }
</source>
*The analog value decides color combination.
<source lang="cpp">
  switch(zone)
  {
  case 0:
    if(color!=0)
      vol[0]=map(v,0,1023,0,255);//Red 
    else
      vol[0]=10;
    break;
  case 1:
    if(color!=1)
      vol[1]=map(v,0,1023,0,255);//Green 
    else
      vol[1]=10;
    break;
  case 2:
    if(color!=2)
      vol[2]=map(v,0,1023,0,255);//Blue 
    else
      vol[2]=10;
    break;
  }
  // Some example procedures showing how to display to the pixels:
  colorWipe(strip.Color(vol[0],vol[1], vol[2]), 20);
</source>

==Hardware Buildup==
*Setup 1：Connect MIC to A0 pin of Sensorhub and Colored LED to A6. Both sides of Sensorhub have pin description, which can be connected with sensors accordingly.

*Setup 2：Connect the activated battery box to BM.

*Setup 3：Stack all modules together without fixed order and finish the circuit buildup.

==Result==
Speak towards MIC and you'll find different effect.
