31  Using Arduino / Project Guidance / Re: Connect 3 accelerometers to Arduino Uno on: November 12, 2012, 08:53:44 am
If you are attaching the sensors to a glove, you may want to consider flex sensors.
Maybe use one 3 axis accelerometer for hand position, and 3 or four flex sensors for the fingers.

The accelerometer could be I2C and the flex sensors wired to the analog pins.

Something like this?

They were used in the Nintendo power glove.

Here is a LCD tutorial from Adafruit:

An accelerometer can be used for sensing vibration.

A multiple axis accelerometer will work better than a single axis.
Then you won't have to guess which axis is better for sensing the vibration.

Since you are trying to sense very low vibration I would try a low g accelerometer, somewhere under 3g.
Sparkfun offers a digital ADXL345? that is 1.5g & 6g selectable, 3 axis accelerometer.  They have a few different types to choose from.
Adafruit offers an analog 3g & 16g, 3 axis accelerometer.

Good luck smiley

It works fine for me.

I am using Adafruit's ADXL335 breakout board for my level project.
I am getting 1/2 degree accuracy.  It will work fine.
