My dietitian requested that i only take a snack once in 2 hours.
Sadly i was not able to figure the time between the snack moments easily.
So, i decided to make a clock that would show when i'm allowed to take a snack again.
When 2 hours are elapsed the clock shows a blinking marker around the clock.
This clock has 3 buttons; the first one notify that i have taken a snack,
the second button shows the remaining time, and the last switches to clock in to a kitchen timer etc.
The display is a MAX7219 Digit Display controlled by an esp32S3 running esphome.
Via the HA dashboard i can see when i toke me snack, what the next snack-time is and tell the timer that i have taken a snack.
