How to show heartbeat or heart rate on arduino?

LCD attached to an Arduino is one possible choice as the Arduino itself has no display of any sort.

.

It cannot use monitor or plotter to show the heartbeat or heart rate?
Then how to show beat on monitor when every heartbeat?

You could blink an LED in time with the heartbeat. There is an LED built in to Arduinos, but of course, the heart rate monitor would be an add-on.

Yes, it can, and very well - but not using the Arduino serial monitor. If you have Excel you can send the data direct using the PLX v2 macro. This will give you the live graphic display you are probably looking for - all for the price of a regular

Serial.print(amplitude);

command. No need to poof about with LEDs or LCDs. If you don't have Excel, now might be a good time to beg, borrow, or steal a copy. Tere are other similar methods.

You may find it more convenient to use a phone instead of a laptop. You can send the same serial data to Android via Bluetooth instead of cable, and get a graphic representation using Bluetooth Graphics Terminal, which is God's gift to the Arduino world.
Both methods also allow you to record the data directly.

Hi,
Welcome to the forum.

Please read the first post in any forum entitled how to use this forum.

What are you trying to accomplish, is there a reason you cannot display it on PC or a display connected to the Arduino?

Thanks.. Tom.. :slight_smile:
