Hello, I have a EEG cups and hoping you all know the EEG cups data is passed through instrumentation amplifier and the data is converted intro readable for machines. So do you have any idea to to transmit data from EEG cups to arduino and then using instrument amplifier to make it readable.
The reason I am asking this is to make it compact and small. If its not possible, then is it possible to make the instrument amplifier smaller like Attiny85 size ?
I think you got that the wrong way round. I'd expect the cups to feed the amplifier and the output of the amplifier to go into the A2D input of the Arduino. An Arduino cannot read an ECG cup directly, the signal needs to be amplified first.
