ABOUT THIS PROJECT
After designing the "Clock Set Date Time" and hearing the suggestion of ArduPic, I thought it would be a good idea and also useful, add a "wake-up alarm." A small change to the code and adding a few components: Here's "the Alarm Clock".
Compared to the previous project, I added a buzzer Piezzo, a diode LED, a resistor of 220 ohms, a button and as said before, I listened to the suggestion of "ArduPic" and I removed the resistance to "pull down."

Testing
After uploading the code, LCD will show a Wrong date and time. It means you need to set the Date and time. also remind to Turn OFF or Set the alarm. if not, It will ring at an unexpected time! You can use UP, OK, DOWN push buttons to navigate trough each menu and set date, time and alarm. once you set the alarm, it will save on the EEPROM of your Arduino. Therefore It never lost if you power off your Alarm Clock.
