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
|
|
analog 4: ground
|
|
analog 5: vcc
