First sketch - Every heartbeat counts

For my first sketch I want to see if technically it is possible to connect between a person's pulse and time.


I recently 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. If your heart rate is raises the the timer will count down but in higher rate:



I bought this sensor:

I used this video to make a count down clock:
