Screaming Monster

Language	English

Objective This project can detect human movement. When someone passes by, it'll send out monster scream. Principle Equipment Module Number Function Microduino-CoreUSB 1 Core board Microduino-Sensorhub 1 Sensor pin board Microduino-TOUCH 1 Touch sensor Microduino-PIR 1 Infrared pyroelectric sensor Microduino-Audio 1 Audio module Microduino-Amplifier 1 Audio power amplifier Microduino-BM 1 Battery management 文件:MicroduinoSkreech.jpg 600px Hardware Buildup Setup 1：Connect the CoreUSB to the computer, open the program examples, select the right board and serial monitor, and then download the program. 文件:MicroduinoSkreech1.jpg 600px Setup2：Connect the Touch sensor to Sensorhub D6 and the PIR to D10. 文件:MicroduinoSkreech2.JPG 800px Setup3：Connect the battery with BM. 文件:MicroduinoSkreech3.JPG 800px Software Debugging Code Description Define the Control Pin #define humanHotSensor 10 #define buttonPin 6 Detect human infrared and play audio. void pirDetector() { // read the input pin: humanHotState = digitalRead(humanHotSensor); // print out the state of the button: //Serial.println(humanHotState); delay(1); // delay in between reads for stability if(humanHotState) { Serial.println("play sound....."); audio_choose(1);// 2:health,1:noHealth audio_play(); } } Judge if some touch the button. void updateButton() { if(key_get(buttonPin,0)) { delay(200); on_off=!on_off; } if(statusChange!=on_off) { statusChange=on_off; if(on_off) { Serial.println("pause"); audio_pause(); } else { Serial.println("pause"); audio_pause(); } } } Program [MicroduinoSkreech] Result It can detect human movement. When someone passes by, it'll scream. By touching the button, it will stop screaming. Video
