首先先介紹一下Ardunio以下是她的官方網站。
http://www.arduino.cc/
簡單來講，如果有電子電機背景的人，在做出一實際有用之電路時，需要經過許多步驟，頗
為麻煩。
但是如果只對其電路其""效果""以及""功能""感興趣的人呢，Ardunio是個非常適合的選擇，其程
式碼簡單易懂，也不必耗費心神在複雜的電路之上，只需專注於其效果以及應用，在國外其
實已經非常風行，而亞洲方面也有許多好玩的東西，只不過像編譯器的開發目前在亞洲並沒
有看到太大的進展。
如果對Ardunio有興趣的人，可以到以下網誌查查其基礎，以及簡單的應用。
cooperma
裡面有許多基本功能的介紹，簡單易懂，我也時常在此查資料。

裡面有些應用，由於我寫程式的實力很弱，如果是資工背景的朋友可以到這個網誌查查其應用

先給大家看一下假的完成品。
功能如下 偵測到頭部動作，送出一個持續且微小的訊號(約2.2V)，使繼電器產生開關，做到
控制的功能。
使用材料:
Ardunio*1MPU 6050*1
電線數條
12V鹵素燈頭燈
繼電器
Ardunio與MPU 6050接角
Ardunio MPU6050
A4 SDA
A5 SCL
3v VCC
GND GND
接好之後要安裝相關library，給編譯器來使用。
(之後會補下載連結)
裝好之後當然就是先開始寫程式啦~

// Arduino Wire library is required if I2Cdev I2CDEV_ARDUINO_WIRE implementation

void setup() {
// join I2C bus (I2Cdev library doesn't do this automatically)
Wire.begin();
// initialize serial communication
// (38400 chosen because it works as well at 8MHz as it does at 16MHz, but
// it's really up to you depending on your project)
Serial.begin(38400);
// initialize device
Serial.println("Initializing I2C devices...");
accelgyro.initialize();
// verify connection
Serial.println("Testing device connections...");
Serial.println(accelgyro.testConnection() ? "MPU6050 connection successful" : "MPU6050 connection failed");
// configure Arduino LED for
pinMode(LED_PIN, OUTPUT);
}
void loop() {
// read raw accel/gyro measurements from device
accelgyro.getMotion6(&ax, &ay, &az, &gx, &gy, &gz);
// these methods (and a few others) are also available
//accelgyro.getAcceleration(&ax, &ay, &az);
//accelgyro.getRotation(&gx, &gy, &gz);
// display tab-separated accel/gyro x/y/z values
Serial.print("a/g:\t");
Serial.print(ax); Serial.print("\t");
Serial.print(ay); Serial.print("\t");
Serial.print(az); Serial.print("\t");
Serial.print(gx); Serial.print("\t");
Serial.print(gy); Serial.print("\t");
Serial.println(gz);
digitalWrite(LED_PIN,high);
}
以上是他給的範例，可以讀出RAWvalue，由於我們的功能是要偵測到動作就送出一個訊號
因此我們可以直接在loop函式內直接加上這樣功能的程式碼即可。

#include <EEPROM.h>
void loop()
{
int address = 5;
int value;
value = EEPROM.read(address);
if(ax<100)
{
EEPROM.write(address, 0);
}
if((ax>100)
{
EEPROM.write(address, 1);
}
if( value < 2 && value > 0)
{
digitalWrite(8,HIGH);
}
if( value < 1 && value > -1 )
{
digitalWrite(LED_PIN,LOW);
}
Serial.println(value);
}
如果直接用
if(gx <100)
{
delay(1000);
}
是可以讓他按一秒，但是delay函式會影響到全部的功能故要較少使用。
