Topic: eye blinking in Neurosky with Arduino (Read 7017 times) previous topic - next topic

Hi
I am a french student and I have a project for the Science of the Engineer section.
In this project we use Arduino for receiving data from the headset Mindwave.
Here is my problem:
I'd use the eye blinking to control a servo motor but I can not get this data, I did search but nothing concrete. Apparently I should initialize arduino to handle that type of data.
I already have a working program, but uses the attention ...
Thank you for your help and sorry for my English.

What extacly you want to read from?
analog or digital?

I'm also encounterin' this problem and I've noticed in the Mindset communication protocole documentation that the eyes blinkin' datas are only availbale with the TGCD and TGC APIs.
I keep searching but and don't have any hopes at all  =(
Please share with us your findings, I will do same.
Cheers

Hi all!
Nathan-NIS I've finally resolved the problem.
If you want to detect the eye blink with your headset Mindwave you should do an unexpected manipulation of your headset  ]:D
I'm joking! the tip is to detect when the EEG datas theta or the raw datas values reach a threshold because eye blinks are artifacts i.e some noise for these values.
When you blink your eyes, you should detect a peack between two raw datas  8)

Can you detect the blinking with the MindWave and Arduino?

Hi Ryan,can you give tutorial for us?
how to get blinkStrength value from the headset..

Hello guys,

I have the same question. How can I get the blink strength value from Mindwave Mobile's EEG signal in Arduino?
I have found the following link on linkedin where you can find useful information on how to enable blink detection in TG_EnableBlinkDetection( int connectionId, int value) function in thinkgear.h file.

But my question still is even if I do that, how can I get the blink strength value in Arduino?

Thank you all.

could you please tell me how to detect?
i got rawValue but it looks random

Ryan_MX Hi, never mind but telling us these things it helps Us no way.
Everyone on the internet can grab these description, but we need at least the code that extracts the raw data in Arduino.. Any other speech is like fried air…
