Arduino Altimeter

04.04.2022: UPDATE
Code has been tweeked to include altitude in meters and feet, also a VSI was added that is approx M/s but not calibrated. The VSI is fairly damped but feel free to hack your own code.
17.12.2021. UPDATE:
The is a 2nd set of models for those printing on an FDM.
Less complex box but with added positions for screwing the cover on.
For the FDM print Bezel lid case 2.
Original cover was not a great fit so this is much more secure.
I am working on adding the Adafruit compass and this should be an easy upgrade as it just plugs in.
Also thinking of adding a volt meter to watch battery level but lower priority.
Enjoy!
So I decided for fun to build a altimeter for my paramotor.
Its very low cost, ok its all relative!
