aquamaqua - by Muhamed Cicak,
I wrote this way back when I was 14 years old, so be mindful of that :)
This is a hobby aquarium monitoring project, written in C++ for esp8266 microcontrollerm, with interactive UI on a TFT display (with switch buttons). The microprocessor reads values from sensors periodically and logs them to the server by connecting to the Wi-Fi (user can choose which wi-fi to connect via GUI and enter the password). The system also shows real time graphs (which I coded from scratch, using only drawBP and drawLine functions from TfT Adafruit library). Graphs are configurable as to what density they should have etc. Object Oriented Programming was extensively used. I basically wrote my own GUI library for TFT where you can easily create textboxes, keyboard interface, shapes, graphs, handle input etc. Also I created a Screen concept where you can construct screens user will go through and what GUI elements will take place on those screens (I think I borrowed this idea from the Unity game engine). Inputs are handled with interrupts, so that the user doesn't have any "lag". I also wrote a wrapper around the interface code for accessing EEPROM to use it easily (I created a similar api to localStorage in web browsers, where you can add data with string key and value pairs and access it easily later on). Most things were written from scratch, even things as basic as a linked list. There's probably some things I left out in this README, from details to features, because it's been quite a while since I last interacted with this project, so feel free to explore the source code youself :-). Cheers!
P.S. This code was run by Platformio plugin VSCode. In lib/ directory you have all of the libraries needed to run the system.
