 ADXL3xx

 Reads an Analog Devices ADXL3xx accelerometer and communicates the

 acceleration to the computer.  The pins used are designed to be easily

 compatible with the breakout boards from Sparkfun, available from:

 The circuit:

 analog 0: accelerometer self test

 analog 1: z-axis

 analog 2: y-axis

 analog 3: x-axis

// these constants describe the pins. They won't change:

const int xpin = A3;                  // x-axis of the accelerometer

const int ypin = A2;                  // y-axis

const int zpin = A1;                  // z-axis (only on 3-axis models)

void setup()

{

  // initialize the serial communications:

  Serial.begin(9600);

}

void loop()

{

  // print the sensor values:

  Serial.print(analogRead(xpin));

  // print a tab between values:

  Serial.print("\t");

  Serial.print(analogRead(ypin));

  // print a tab between values:

  Serial.print("\t");

  Serial.print(analogRead(zpin));

  Serial.println();

  // delay before next reading:

  delay(100);
