Introduction

This work is the output of my first self-learning Arduino. After COVID-19, many people unfortunately passed away. So I thought about death. We often think of death as passing away, but death is the norm in the long history of mankind. Why is "birth" not a test? Why is death not our destination and origin? The meaning of death seems to have always been a topic that people avoid. People often use falling leaves as a symbol of death, which I think is very pessimistic. Death is the last thing we need to do, and actively doing it well brings a happy ending to life.
So I made a final device—a bouquet that extinguished the lights when I breathed. The sensor detects when the user's pulse beats and turns off the light. Finally when the user dies, the bouquet will light up forever. I hope that through this form, people can rethink death.
