HC-SR04 Ultrasonic Distance Sensor library for Arduino

A collection of commonly used math routines, so I don't have to write them again. Implementations in C, C++, Rust, and Python (though not so much in Python as it already has a pretty good set of libraries).

Sparkfun MCU-based parking sensor.

CPP Geometry Library provides utility functions for the computation of geometric data on the surface of the Earth.
