The Smart Alarm Mat is a creative alarm system built with an Arduino Nano, designed to force you out of bed! Instead of just pressing a snooze button, you must stand on the mat for a few seconds to stop the alarm. It uses a pressure sensor, RTC module, LCD display, and a buzzer to wake you up and ensure you’re really out of bed. Ideal for heavy sleepers or anyone trying to build better morning habits.

Initialization:
Arduino sets up the RTC, LCD, buzzer pin, and button pin. It reads the alarm time from EEPROM memory (non-volatile storage).
Display time:
Every loop, the Arduino reads the current time from RTC and shows the day, date, and time on the LCD.
Check alarm:
When current time matches the saved alarm time and the alarm hasn’t rung yet today, the buzzer starts sounding, and the LCD shows “Alarm!”.
Stop alarm:
If the button is pressed, the alarm enters a "stopping" mode for 10 seconds, then the buzzer stops, and the alarm is disabled until the next day.
Reset daily alarm:
At midnight, the alarm status resets so it can ring again the next day.
