Digital clock using 7 segment display controlled using TV remote

Zxlee wrote a post on his blog detailing his digital clock on 7 segment controlled with TV remote:

When the Arduino first power up, it will display time information on 7 segment displays. Besides that, the LCD will display the time, date, temperature and day of week information. Basically, this is the main part of the program. The program will keeps on read from the DS1307 to update the time information.
When the user pressed ‘menu’ button on the TV remote, the LCD will display the selection for menu function. The functions available are alarm, timer, stopwatch and settings. User can navigate through each function by the ‘+/-‘ button. Whenever the user decides a function, the user can press the ‘select’ to enter that particular function.
