A generic doubly-linked list template implemented in C++ for Arduino. It provides push, pop, insert, remove, and iteration operations. The implementation is self-contained (no internal dependencies) and can be extracted for any embedded project needing a lightweight list. Demonstrates clean template usage and memory management for constrained environments.

A timed FIFO task queue for sequencing robot actions. Tasks are stored with a delay and executed in order. The implementation is independent of the robot hardware and can be reused in any embedded system requiring non-blocking sequential operations. It uses a simple struct and linked list pattern, making it easy to port.

A generic I2C read/write abstraction library supporting multiple backends (Wire, Fastwire, NBWire). It provides functions for reading/writing bytes, words, and buffers with error handling. This is a standalone component that can be reused for any I2C sensor on Arduino-compatible platforms. The code is well-structured and includes timeout and retry logic.

A simple translation system using a dictionary of language dictionaries. It provides a `txt(key)` function to look up strings in the selected language. The pattern is self-contained and can be extracted for any Python GUI application needing multi-language support. It demonstrates a clean, data-driven approach to i18n without external dependencies.
