Hello guys, as you can see, I'm a freshman in this forum and, as you can't see, so in Arduino world. I'm working on a project that I have to make my Arduino read a .txt doc full of dates and hours of reunions in SD card and make the comparison with the actual date and hour to, after that, do something or don't do something(if the date is equal and so the hour, Arduino won't let someone enter to the room). But I've never programmed an Arduino and i have no idea how start it. Can you help me guys ?
P.S.:Sorry if I had some grammar error, english isn't my first language and has a time I don't practice it;
