An Arduino Uno provides the processing power and drives the serial monitor. A joystick and a Hitachi H48C accelerometer are mounted on a breadboard and wired to the Uno.

The processing code works (with Arduino connected of course) if you see it run and color in box changes properly. If not, change the serial port number in the code. If it still doesn't work, ...

The software part employs three development platforms: Arduino IDE, Atmel Studio 7, and Processing. System-wise, everything plugged together in a sequence that made sense and just worked.

The Arduino software environment, including the IDE, libraries, and general approach, are geared toward education. It’s meant as a way to introduce embedded development to newbies. This is a … ...

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).
