In now days pandemic it will be helpful if you can check your heart rate, so I have created this.

I have shown you how the project works once it has been coded I hope you will like the project, and basically we have used a heart rate sensor we take readings for some seconds and then it displays it on the lcd screen, its cool right to have your own heart rate detection device I have given the scheamatics for connections and my code as well.

In the scheamatics there are three pins for KY039 heart rate sensor ,connect the S pin to Analog pin 0; 5v pin to 5v pin on arduino; Gnd pin to Gnd pin on arduino ;

I hope you will be knowing how to connect the lcd screen to arduino as it is very easy thing.”
