Plangotchi is kind of a Tamagochi, the only difference is that it's made based on an ESP-32 programmed using C++ language and a Python script.
The script in C++ is responsible to integrate the sensors that read humidity, luminosity, presence and send the data to a Firebase database, and to display the data on a lcd too.
The script in Python is responsible to consume the data of the database and calculate Plangotchi's humor and reproduce sounds based on it.
