The Sunrise Alarm Clock project is a silent light-based alarm. Using an LED light strip or board, this project will simulate the rising sun to wake up the user with light.

This board interfaces with an Adafruit DS3231 breakout board and a 7 segment display breakout board.

In the current revision, there is no method for writing the time to the DS3231 module. Use female header to allow the removal of the module. Use a Raspberry Pi or equivalent to set the time over NTP.

Major Components

  • Atmega328P-AU

  • Adafruit DS3231 Breakout

  • Adafruit Red 7-segment LED Breakout

  • LD1086BDTTR 5-volt linear regulator
