- [2020] – MVHR Bypass (IoT Device + Android Companion App – Open Source) 📱🎛️
- IOT device able to control the MVHR Summer Bypass, based on inside and outside temperatures.
- This is a passion project that I wanted to create for a very long time, particularly understanding how microcontrollers work at a low level, and successfully programming them to solve a real-world problem.
- Once I started the project, it was so fun that I wanted to go past what I initially planned, so I also integrated an ESP8266 WiFi Module and programmed it to act like a bridge between the main Atmega328p chip and the client Android App, which allows to remotely monitor the 4 temperature sensors and control target temperatures for the bypass.
- The project is split into 4 repos:
- mvhr-bypass-common – Contains the main readme file describing the entire project, common code which is included in both the Atmega328p chip and the ESP8266 chip and extra resources (C++)
- mvhr-bypass-arduino – Code running on the Atmega328p chip, controlling the LCD display, receiving user input through push buttons, reading temperature sensors, holding the bypass trigger logic and communicating with the ESP8266 WiFi Module (C++, Arduino Libraries)
- mvhr-bypass-esp8266 – Code for the ESP8266, running a socket server for network clients and communicating with the Atmega328p through serial connection (C++, ArduinoJson, WebSocketsServer)
- mvhr-bypass-android – Android client app, which connects to the ESP8266 via Sockets (Kotlin, Koin, OkHttp, Custom Views, MVVM Pattern)
