Concept:-
The idea is basically, I would be using a pulse sensor to display the heart rate onto the screen and play around with it to see if I can do something cool.
I would try to represent the data provided by the pulse sensor to make a pulse/ heart rate and some variations.
I would also want to add the buzzer to make different sounds for different rates, which I think would be pretty cool!
I think I’ll get more ideas after I start playing with the sensor and get some feedback on the basis of that.
