I've developed an experimental ESP32 project that simulates a heartbeat pattern. But I don't have a heart rate sensor, I used my normal resting heart rate as a basis for the simulation. The project utilizes an ESP32 to create a LED blink pattern that represents a heartbeat, starting at a faster rate and gradually slowing down to a resting rate.

Here's the link to the project: https://github.com/Qiaogun/ADHD_Blink
