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?
