Making a led changing intensity depending on heartbeat

Other Hardware Sensors
1

Hello
I'm a beginner, I'd like to know how can I program an arduino to change the light intensity depending on the intensity of hearbeat, and which arduino should I use for this project,

Thank you so much for helping

If by intensity, you mean being able to dim the LED, any Arduino could do the job.

As this is a fairly easy task , any Arduino product would do the job . if you are starting out a genuine UNO from the Arduino store is a good move for this and later projects .

Go for one of the little heartbeat/pulse sensors , dont be tempted to make your own or start connecting wires to people .

Have a google for led fade examples for some code ideas . If you buy a heartbeat sensor , you can get one with code examples

Intensity of heartbeat as in the strength of the pulse or the rate of the pulse? Heartbeat sensors tend to measure the latter.

You got me with "depending on the intensity of heartbeat" as to how we define intensity of a heartbeat. I see it as mentioned, the strength or pressure of the pulse verse the rate of the pulse.
