Purpose

To control the color of a lantern by detecting sound via mic sound detection sensor.

Principle

Equipment

Hardware Buildup

• Setup 1：Stack CoreUSB and Sensorhub.

• Setup 2：Connect Sound to A0 pin of Sensorhub and the colored LED light to A6. There is pin description on both sides of Sensorhub, which can be connected sensors correspondingly.

Software Debugging

• Setup 1：Build development environment, connect CoreUSB to your PC and download program code.

• Setup 2：Code description: One part reads analog values and the other controls color combination of the lantern according to the values.
  • Read analog values.

int v=analogRead(A0);

• • Color quantization

  switch(zone)
  {
  case 0:
    if(color!=0)
      vol[0]=map(v,0,1023,0,255);
    else
      vol[0]=10;
    break;
  case 1:
    if(color!=1)
      vol[1]=map(v,0,1023,0,255);
    else
      vol[1]=10;
    break;
  case 2:
    if(color!=2)
      vol[2]=map(v,0,1023,0,255);
    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);

Result

Speak towards mic and you’ll be surprised about the effect.
