Objective

Say "Cheese!" towards MIC, it will send out infrared signal and at the same time, the camera will take a picture.

Principle

Equipment

Program Download

• Setup 1：Connect CoreUSB and your PC/Mac with a USB cable, and then open Arduino IDE.

• Setup 2：Click file > example> mCookie > _204_JoyfulGreeter

• Setup 3：Select the right board and COM port, and then download the program.

Software Debugging

• Define Sony camera infrared transmitting code

#define PHOTO 0xB4B8F

• Control pin definition

#define mic_pin A0
#define IR_pin 6

• Sound trigger value

#define voice 400#define voice 400

• When the sound is louder than the trigger value, the camera will be triggered after a period of time delay and counting. The time delay is decided by function values of "num" and "delay". Users can also change the related parameters can have a try. Taking picture is controlled by the function "take", which can only send photographing instruction once.

  if (voice_data > voice && take == false)
  {
    time = millis();
    num++;
    delay(10);
    Serial.println(num);
    if (num > 20)
    {
      take = true;
      takePhoto();
      Serial.println("takePhoto...");
    }
  }

• The next shot can be triggered one second later after detecting no sound.

  else if (millis() - time > 1000 )//Take pictures after one second.   {
    voice_data = analogRead(mic_pin);
    if (voice_data < voice)
    {
      num = 0;
      take = false;
    }
    time = millis();
  }

• Send photographing instruction function

 void takePhoto()
{
  for (int i = 0; i < 3; i++)
  {
    irsend.sendSony(PHOTO, 20); // Sony code
    delay(10);
  }
}

Hardware Buildup

• Setup1：Connect MIC sensor to A0 pin of the Sensorhub and infrared transmitting sensor to D6 pin.

• Setup2：Connect the activated battery box and BM module.

• Setup3：Stack all modules together without fixed order and finish the buildup.

Caution

Result

Yell at MIC and trigger the camera.
