So I bought a touch screen from ebay and it comes with an sd card. I want to make an alarm clock that reads preset alarm times from the sd card. I already have an RTC module. I'm at a loss on where to begin coding and hardware wise. I'm just getting back into working with arduino. Any ideas on how to start?
The best option is to contact the supplier via eBay and get them to send you links to libraries for this board.
Or if they can't do that ..
Track down the docs from the manufacturer e.g. the website written on the board
Or if you can read any of the writing on the IC's you could try to find a library for those IC's
