Code for an alarm clock based on arduino nano and an RTC module

ArduSveglia

DS3231 RTC module Alarm clock based, featuring an arduino nano Atmega328. Simple but effective code, written in a Super-Loop style. An LCD display is used along with its I2C module for communication. Big Fonts are integrated inside the project because also eyes life matter.

3 buttons to set all parameters:

• P1: change menu page by clicking
• P2, P3: use to increment time or date

On page 0 (TIME):

• P1: change page
• P2: increment hours
• P3: increment minutes

On page 1 (TEMP):

• P1: change page
• P2: nothing
• P3: nothing

On page 2 (ALARM):

• P1: change page
• P2: increment hours
• P3: increment minutes
• P1: long press (>2s), turn on/off the alarm. The LED will show the status.

On page 3 (DATE):

• P1: change page
• P2: select parameter to change a number at bottom right corner will be displayed 0: use P3 to increment day 1: use P3 to increment month 2: use P3 to increment year
• P3: increment values

A RGB led is light up 15 minutes before alarm turns on, different colours will show up to simulate sunrise A buzzer is used to play an alarm. Long press P1 to turn off the alarm when ringing.
