I started off today by soldering together the DS1307 RTC kit and hooking it up to the Uno. After running the example program that sets the time, I wrote a function called updateTime() that takes the place of demo(), but hands off the actual time instead of the minutes looping over and over. This worked out fine, and as of now, the Trinket Watch was a functioning bedside clock! I also polished off my stopwatch mode, which works just fine. Video below, with some more Pong as well:
