Various code snips for MCUs. This includes short sketches for:

• Arduino R3 UNO
• Arduino R4 UNO
• Huzzah Feather ESP8266
• FireBeetle ESP8266

• ESP32 Dev Boards

  This is primarily a learning repository. However, it also contains work related to a university learning project. See Water Quality Measuring Project.

Version 1 prototype code allows:

• I2C communication between 4 MCUs
• Arduino R3, Huzzah Feather 8266, and Firebeetle ESP8266
• Multi-sensor parameter measurement unified into one system (for water)
• Code to connect to thinger.io and deliver basic data
• Code designed in Arduino IDE

There are several operational issues with the Version 1 design, and it is suitable for lab only. Version 1 was designed as part of a HAMK University Program module on learning microcontrollers. While it may have the intended functionality, the real purpose was to learn MCU functions, operations, basic C++, and the I2C protocol. However, the objectives can easily be reduced into a smaller, contained system.

Version 2 prototype code allows:

• I2C communication between 2 MCUs
• Initially ESP32 Dev Module, LilyGo SIM808
• Multi-sensor parameter measurement unified into one system (for water)
• Code to connect to thinger.io and deliver basic data
• Code designed in Visual Studio Code using Platform IO

Version 2 is in design, and will be the first implementation to be used in an underwater environment.

Note: I use Wi-Fi for initial testing. However, once the operational design matures, it will naturally transition to low-power communications.
