this is my first "published" project on M5Stack and on github.
I used Uiflow, I initially wanted to use the Calculator Face but the way it manages the numbers is not very easy so I switched to Gameboy Face.
it's a thermal sensor for liquids with predefined beverage or liquid (for example tea, coffee, bath...)

It uses up and down to select a liquid and set the temperature and the time (for the tea for example).
It uses right and left to manually set the temperature.
"start" set the alarm on/off
"A" starts the countdown and "B" stops it.

For now it's only in french but if it's interesting some people, I can translate it in english.
