Hello. I am trying to start a project with the Uno that involves making an audio advent calendar for Christmas and other holidays. For ease of use I would prefer to use both an LCD shield and a Wave Shield, because then I can buy a smaller breadboard that contains only the RTC I will need for the project. The LCD shield also conveniently comes with pushbuttons that would be handy for allowing me to set the clock and the holiday that the calendar is counting down to.
Is it possible to stack the LCD shield on top of the Wave shield and then connect the RTC to the I2C connection on the assembly? If so, would anyone have a suggestion as to a good RTC to use?
I do not see any pins that would interfere with one another, but I don't know if I might run into an issue where I accidentally buy an RTC with the same fixed address as the LCD shield.
LCD Shield + Wave Shield + RTC: Possible?

That should be possible. We have DS1307 RTC modules and the slightly more accurate Chronodots.
