The heartbeat sensor has three sets of data.
heartbeat/minute (we can make it change by encouraging audiences to do activities/ exercises. 2. pulse width
Oxygen level (always stable)
-One possible solution: design a game to make people exercise, thus increasing the heartbeat rate; then, we can make different LED effect when the player reach a certain beat level and etc.
I made the lights blink with the pulse of the heartbeat.
But it’s unstable….
