February 10, 2012 [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.

An accelerometer reads hand motions and sends them via an RF module to an Arduino. This is a bit of a trick, because the device produces an analog value and [Saddam] uses some comparators to ...

Essentially, it is another safety initiative that gives a visual warning of a biker braking, with LEDs tucking up the end of the handlebars. It is based on an 3-axis accelerometer board, provided by ...

The helmet is equipped with LED lights that are controlled by the Arduino Nano. When the motorbike’s indicators are activated, the Arduino Uno sends a signal to the Arduino Nano, which then ...

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).
