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();
    if (num > 20)
      take = true;
  • 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

Hardware Buildup

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