Warning about the ADXL335 and the Arduino
21st February 2010
SparkFun have an excellent range of accelerometer breakout boards for hobbyists, mostly based on the ADXL3xx series of chips. The vast majority of these are happy to run at 2.4V-5.25V and so can easily be plugged directly into the Arduino. Unfortunately the ADXL335, which I believe to be the newest and cheapest chip, does not accept any higher than 3.3V.
