I suggest you stop at this point and get a copy of the Arduino Cookbook and read it trying any of the programs that interest you. Also there are many great tutorials on line. The common programing language for the Arduino is is C++ or python.

"Regular little LEDs" are easy to dim. LED "light bulbs" and "high-power" LEDs are more tricky.
Although you can "delay" for 12 hours, the clock in the Arduino usually isn't very accurate and it will drift. If you need accuracy for several days or more you can use a "real time clock" module. You'll have to research how to use it. There are also ways of getting the time with a GPS module or over the Internet and that's more accurate than a real time clock module because they use atomic clocks.
