Adding opto-isolater to mindflex

[r-bt]

Hi all, I have a mindflex headset which I have set up according to this tutorial(http://www.frontiernerds.com/brain-hack) however the signal strength never reaches 0 and as such I cannot get the attention/meditation values. I tried adding salt water and that worked for a while but ultimately it stopped. So I purchased and opto-isolator(http://www.maplin.ie/p/high-voltage-opto-isolator-ay44x) but I am stuck at how I am meant to wire it up to the arduino and minflex.

Any help would be greatly appreciated. Richard

I would like to know too!

how would an optoisolator solve that problem?

Closing this as it's not related to a specific issue with the library.

Perhaps an opto-isolator it could prevent noise between the Arduino and the TGAM, but given everything that's already going on right on the TGAM board, that seems a bit a bit superstitious.
