in short idea is to connect the 2 mux between the electrodes and the amplifier then connect the amp output to my Arduino UNO
in detail, I have 13 electrodes (6- and 6+) with one reference and the amp board here
what I am planning to do is to connect 6- electrodes with mux 1 and 6+ electrodes with mux2 then form Arduino i will control mux1 and mux2 to output the incoming signals from electrodes and feed them to the amp board respectively then feed the output from the board back to Arduino so I be able to store and analyze the signals related to each electrode pair independently
something like this Arduino --> [1,1] [2,2] [3,3] [4,4] [5,5] [6,6] -->amp-->ardino
My question is, will this method be possible? If so, will the processing speed of Arduino be fast enough to handle this task?
Yes, if I’m understanding your question correctly, it may be possible. However, the link you provided is for a sensor, not an amplifier. Please post your proposed annotated schematic along with links to each of the hardware components.
As for speed, there shouldn’t be any issues if you have an hour or so. If you need a faster response, we’ll need to know what your specific response criteria are.
Doubtful, but hard to say without complete details of the individual components, a schematic diagram and a demonstrated understanding of noise reduction techniques.
Because the signals are so tiny, an amplifier for each set of electrodes is by far the best approach for beginners. The Arduino ADC is already multiplexed, typically with 6 or more inputs.
