New version of :

Garbage display

New schematic using ESPHOME and has reset button (pressing the lid).
(Resets the LED when you’ve put the trash at the street curb.)

Above, a simplified version. I’m using 4 ws2812 leds now.

ESPHOME code:

esphome:
  name: afvalwemos
  friendly_name: AfvalWemos
  on_boot:
    priority: 800
    then:
    - delay: 1s
    - light.turn_off: main_leds
