Every heartbeat counts

I read a study that claims that a people have a limited number of heartbeats in their lives (around 3.3 billion). I wanted to show that with a timer that counts down all the time based on your heart rate - a reminder that all things must come to an end and that our time is the most precious thing we have


I started with this sketch that created a simple countdown:


Then I connected all the number and ran their code in the Arduino


In order to measure the heart rate I bought a simple fitness watch. I used bluethooth and this website:

https://vshymanskyy.github.io/miband-js/

in order to check if I can get real live heart-rate data.

I used this code:

https://github.com/vshymanskyy/miband-js

In order to connect between the p5 and the watch.


Then I wrote all the code in my first p5 sketch in order to connect between 3 things:

the Arduino, the countdown numbers (p5), bluethooth (the watch)


For the fabrication

I started with a sketch


Created a mold using disposable bowls:






This is the final result
