Grove Heart Rate Ear Clip and HRV


I’m a complete beginner and would really appreciate some good advice. I’m trying to build a simple biofeedback device showing heart rate variability with this piece of kit, an arduino mega 2560 and a win 7 laptop

I’ve managed to get the earpiece working, led flashing in time and outputting to the com port. I’ve downloaded brainbay but cannot get a signal in no matter what input settings I use.

Anyone managed to a) get brainbay working with the Grove and b) Worked out how to display HRV for meditation, relaxation purposes?


Hi, also - has anyone got the grove ear clip to work with the processing code?
