a help in my project (EEG with arduino)

hello every one i hope that you are fine i need to contact some one who has experience in building an eeg circuit with arduino i have a project and i have every thing to do it just i need some one to guide me and help me in somethings if just you can i hope that i will find some one to help me

What help is it You ask for?

i have some questions for personnes who have already release an eeg with arduino

"i have some questions for personnes who have already release an eeg with arduino"

Use the forum Google search function in the upper right of this page to search for the key words of your project. You will probably find many similar previous project discussions and code to get you started.

Hi,
Welcome to the forum.

Please read the post at the start of any forum , entitled "How to use this Forum".

google arduino eeg

Thanks.. Tom... :slight_smile:

Building an EEG circuit is nothing for a beginner. Kind of a headset is required, with multiple electrodes and amplifiers for those very weak signals. The rest is standard Arduino code and libraries, depending on what you want to do with the signals.

thanks for you all
i really read a lot about this project in google but still have some questions
such as
if i can't find th AD620AN what should i put instead of ? if i should put some op-amps how the circuit will look like ? are every op-amps working the same way ?

Hi,

Can you tell us your electronics, programming, arduino, hardware experience?

If very little, then you will need to begin by getting used to the Arduino IDE, programming and electronics hardware.

Is this an academic/school project?

Thanks.. Tom.. :slight_smile:

no it is not very little
you can say that i am a little bit old in working with arduino
so i am a young girl so my school consider me as a genius
and i have a lot of projects i work at them
just myself
please help me

Genius is not enough, knowledge is required as well. If you don't know how the circuit works, and which may be a reasonable replacement opamp, you should study electronics until you can answer these questions yourself. Until then it's less frustrating to use and study ready-made EEG amplifiers.

"please help me"

Well, also learn to help yourself. Using the forum search function I previously suggested, below is your basic background reading homework assignment on the arduino and EEG projects. This should provide enough information as to the practicality of your project.

thanks for your advice
i’ve been learning a lot about that
but still have those questions
knowledge is the best thing ever
i will try again to read more things
thanks any way

thanks a lot

i read as you device me
about op-amps and instrumentation amplifier
i know now what to put instead of AD620
because i can't have it
look at this picture

i think that i can build an amplifier like AD620 from those three op-amps
then i will work with arduino like if i am using an AD620
is that right ?

Right, build the circuit and try to use it in your project. It should work if you did everything right, if not you have to find out why not.

Using so called low noice OP-Amps, shielded cables, shielding box etc. it might work.

Hi,
Ops circuit;


It is an instrumentation configured opamp, should give good stability.

Tom... :slight_smile:

so i think when i make this shematic
look like a circuit it will look like

(don't care about the resistances values i will change them later )
is that right ?

which op-amp is more good for this project
i read a lot and i find that i can use any op-amp
but please advice me which is more good
24C64 or G2992

Buy both and build a test circuit with both chips, then you can find out whether it makes a difference in your project.
