hallo everybody! I'd like to build a clock with arduino, but I have some problems: I read online that the chip "ds1307" is commonly used, while someone uses a "PCF8593". could someone explin me what's the difference between these two, and which one should I choose?
(please notice that my knowledge in programming is quite basic, so I'd like to find also some code samples or at least hints for developing the clock)
Thanks a lot to whomever (or "whoever"?) is going to answer my questions Ale
