So I am trying to help my simulation lab out at my school and have decided to try my hand at an Arduino project. To sum it up. I want a simple Arduino project that would sense when I passed a wire through a tube and when it got to a sensor it would flash a heart rhythm on a computer monitor. Unfortunately the simlab director feels that instead of just 2 static jpg of heart rhythms on the screen he would like a live rhythm on the computer screen. I am not really sure how I could code a heart rhythm generator. I have spent a number of hours on youtube and forums and have not come up with a whole lot. I was hoping there would be some code out there I could use. I am a very amateur programmer so any help any you could provide would be great. My starting questions are what computer language interfaces the best with Arduino? I was going try this with processing but am open to suggestions. I am also not very sure how to send commands to a computer from my arduino. Thanks for any help you can provide.
Hi, just a quick trawl on google for "simulating ecg signal arduino" bought up this link.
Hope it helps, interesting project as an instructuonal tool, stage prop etc....

Hey Tom,
I ran across that when I was doing my research. Unfortunately tutorial is to generate a heart rhythm on a actual patient monitor. I want to generate a heart rhythm on my computer screen. Any ideas if processing would be a good language to try to do this with?
