Is our solution to achieve our goal smart? (Writing the current logid every time a button is pressed to a .txt on the SD card and reading when we start up the Arduino?)Is our solution achievable with Arduino? (First reading the .txt at the startup of the Arduino; adding it to our long id variable in our code, rewriting the .txt everytime a button is pressed with the correct current logid, as well as putting our formatted line in the .csv file)?
We do not want to parse a potentially big .csv file.
