Step 1:Open the Demo: Calibration and upload it to Arduino.Please click here if you do not know how to upload. The sensor is analog device, you should regulate the sensor before combining it to you system. Download the File: 3-Axis Analog Accelerometer Library and Unzip it into the libraries file of Arduino IDE by the path.The VCC connect to power source（DC5V or DC3.3V）, GND to ground, X to Arduino analog port A0, Y to A1, Z to A2.

The sensor's outline is breakout board, you can welding wire in the board or use jumper wire to connect the sensor.

The following program code includes first-order filter which can make the output smoothly if the sensor was used in robot or toy car. The sensor combined 3.3 and 5V power supply, can be used in standard Arduino device and Seeeduino Stalker. But the board outline is grove module that you can fix it conveniently like other groves. The module was designed as breakout board because ADX元35's signal is analog( more ports requested ). The product measures acceleration with a minimum full-scale range of ☓ g.

The ADX元35 is a small, thin, low power, complete 3-axis accelerometer with signal conditioned voltage outputs.
