Accelerometer ADXL335 with Explore M3

The ADXL335 is an three axis analog accelerometer which outputs raw X, Y and Z axis values on three pins. Let's connect these to the analog input pins on Explore M3 and log the data to the serial monitor.

Hookup

Explore M3	ADXL335
5v	5v
GND	GND
A3	X axis pin
A2	Y axis pin
A1	Z axis pin

Code

This is a standard Arduino example that I will be using. We will make a tutorial some time later to do some math and put the accelerometer to good use.

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