I am about to begin a project and thought I would get the insight of some more experienced Arduino users (I have only been using Arduino for a month so any help is appreciated).
Basically I am conducting an experiment to test muscles spasms in a patient's cheek. They will wear a bandage with electrodes on it. The EMG signals from the bandage will be amplified and sent to the Arduino's A to D converters. Every signal must be time stamped and a signal must be taken maybe twice to ten times a second (I have not decided yet). Then I will load the signal's value and the respective timestamp into an array which will then be saved on a micro SD card. The data will then be sent to MATLAB for analysis etc etc.
Seems simple when I write it out like that, but being a noob on Arduino there are simple things that I just don't even know how to do. how do I convert the EEG signals to arduino? Do the A/D pins do this automatically? I know there is a millis() function that I will use to track time, and assign it to a EEG value.
If anyone has done anything like this and has some sample code, it would be much appreciated. ANY insight whatsoever would help. How would you go about coding/solving this project? Thank you to all.
