Language	English

Objective Say "Cheese!" towards MIC, it will send out infrared signal and at the same time, the camera will take a picture. 600px Principle 600px Equipment Module Number Function mCookie-CoreUSB 1 Core board mCookie-Hub 1 Sensor pin board mCookie-BM 1 Battery management Microduino-Microphone 1 Sound detection sensor Microduino-IR Emitter 1 Infrared transmitting sensor 600px Program Download Setup 1：Connect CoreUSB and your PC/Mac with a USB cable, and then open Arduino IDE. 600px Setup 2：Click file > example> mCookie > _204_JoyfulGreeter 600px Setup 3：Select the right board and COM port, and then download the program. 600px 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. 600px Setup2：Connect the activated battery box and BM module. Setup3：Stack all modules together without fixed order and finish the buildup. 600px Caution 600px Result Yell at MIC and trigger the camera. 600px Video
