[Boris Landoni] put together a guide to using an inexpensive 3-axis accelerometer with Arduino. The chip that he chose for the exercise is an MMA7455L made by Freescale. It’s got a lot of nice ...

This jump occurs because there is no position feedback to the Arduino ... for a MEMS accelerometer is basically a variable capacitor. One plate is fixed and the other mounted some distance away ...

With it, via I2C, I could add an Arduino Pro Mini, and an I2C Oled Display and make a watch capable of having all this information, plus a pedometer (by analysing accelerometer data). Cool enough ...

How do these electronic devices measure motion? Try this activity to find out! Background You're probably familiar with the units we use to measure distance and velocity. In the U.S., we might say ...
