==Introduction==
[[File:Adxl335 1.jpg]]

This is a breakout board for Analog Devices analog 3 axis accelormeter. The ADXL335 is a small, thin, low power, complete 3-axis accel-erometer with signal conditioned voltage outputs. The product measures acceleration with a minimum full-scale range of ±3 g. It can measure the static acceleration of gravity in tilt-sensing applications, as well as dynamic acceleration resulting from motion, shock, or vibration.
The user selects the bandwidth of the accelerometer using the CX, CY, and CZ capacitors at the XOUT, YOUT, and ZOUT pins. Bandwidths can be selected to suit the application, with a range of 0.5 Hz to 1600 Hz for the X and Y axes, and a range of 0.5 Hz to 550 Hz for the Z axis.

==Features==
*3-axis sensing
*full-scale range of ±3 g
*Low power : 350 μA (typical)
*Single-supply operation: 1.8 V to 3.6 V
*10,000 g shock survival
*Excellent temperature stability
*BW adjustment with a single capacitor per axis
*RoHS/WEEE lead-free compliant

Here is the guide illustrates how to connect an Arduino to the ADXL335 breakout board. The following is a table describing which pins on the Arduino should be connected to the pins on the accelerometer:

==Example code==
// these constants describe the pins. They won't change:
const int xpin = A1; // x-axis of the accelerometer
const int ypin = A2; // y-axis

int sampleDelay = 500; //number of milliseconds between readings
void setup()
{
// initialize the serial communications:
Serial.begin(9600);

//Make sure the analog-to-digital converter takes its reference voltage from
// the AREF pin
pinMode(xpin, INPUT);
