Thank you for reading this post!
I am a high school student with very little knowledge in programming, and hardly no knowledge of the Arduino. In my biology research I have to read precise voltage (maximum error of about 3 millivolts if possible) between two points on a large cell (5cm-10cm diameter), have my laptop analyze the data, and send corresponding stimuli (fairly strong light) to the cell.
I am having trouble with the first step: reading voltage.
I have come to the conclusion that it is best to use Arduino for the whole project, but can I read such precise voltage by 1) using 1.1V internal reference; 2) amplifying signal (if so, how can I?); or 3) a completely different method?
I am sorry if this is a stupid newbie question. Thank you for reading! Solutions will be much appreciated!
