This crazy alarm clock will surely wake you up, even when you're in deep sleep! It has an ultra-loud bike horn which might be useful/disappointing for your neighbor too (depends). That's why I don't suggest this thing if you're living in an apartment or if you have rude neighbors (use it at your own risk). However, you can replace the horn with a super bright LED panel which will probably be enough to open up your eyes + not disturb others.
If that super loud horn still isn't enough to wake you up and disable the alarm within 30 seconds, a servo motor with a connected cup of water will be triggered and will hence throw water on you. To still be asleep, you must be dead or from another planet.
The clock is powered by DS1307 based real time clock module, which has the ability to store/process the time and date. It is powered independently by a small 3v coin cell and can run for over an year, thus allowing the clock to display real time even after it has been restarted. Rest of the work is done by the arduino nano used here, which displays the time on a 16x2 LCD. With the help of 3 buttons, desired alarm time can be set which gets feeded into internal EEPROM of arduino. This means that the alarm time won't change even if you switch off and restart the clock.
Disabling the alarm is not as simple as just pressing a button (otherwise it would have failed the main purpose of this project). Two LEDs are connected over two buttons, so the user will have to press the button corresponding to the LED which glows. This has to be repeated 5 times. If the user does't wake up within 30 seconds of the alarm getting triggered, arduino will direct the servo to rotate and throw water (as mentioned above). The horn will still keep on ringing (after 30 seconds), with the LCD displaying a message to restart the clock now (failing to disable).
