Say Cheese

Language:	English  • 中文

Objective Say "Cheese!" towards MIC, it will send out infrared signal and at the same time, the camera will take a picture. Principle 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 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 > _205_SayCheese 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. Video
