Don't forget that you can add a relay board (to control things) and also an ethernet/wireless shield if you want to control things via a web interface.

Besides the DS1307 RTC, you can also consider using the DS3231 chip; it does not cost significantly more than the DS1307.

Something like this (though this is an old photo; I've cleaned up the wiring, added a few components and switched to the TFT LCD Touchscreen)
