Accelerometer Calibration I: Introduction

In my last post I described how to start reading data from an ADXL335 accelerometer with an Arduino and convert those voltage readings into standard units. I even showed some real data coming out of my device and when you … Continue reading

Getting Started with Accelerometers and Micro-controllers: Arduino + ADXL335

My first home electronics project — a device to measure leg acceleration and balance while skiing — involved connecting an ADXL335 on a Sparkfun breakout board to an Arduino Uno.  Going in, I was an experienced programmer but knew nothing … Continue reading
