New features are given their own #define/#ifdef combination, and the #define is commented out until I consider the new feature to be ready. It seems to have worked well these past several years.

All features also undergo testing on three separate test platforms, before I consider them ready. I have a JellyBeanDriver MPGuino that doubles as my Magnum's fuel monitor, I have an Arduino AtMega2560 with a 5-position Parallax analog joystick and a Parallax serial LCD module, and I have a TinkerKit! LCD module with another Parallax 5-position analog joystick (the TinkerKit! LCD module is nothing more than an Arduino Leonardo with an attached HD44780-compatible 16x2 LCD display, and a few handy electrical connectors).

My testing mainly makes sure that the feature in question actually works as intended. Secondary concerns (e.g., the horsepower readout on the accel test feature shows "PSI" instead of "HP") will be worked on as time permits.

I get these errors when I tried to compile your code just now. Does your code require an obsolete version of Arduino IDE for successful compilation?

Code:
