“CarpeDiemAlarmClock is an alarm clock that is waking you up “gently” by gradually increasing the intensity of a NeoPixel LED-ring, before the alarm hits.
The alarm clock shall also has an option to sound a buzzer at alarm time.
User must be able to set clock and alarm time
The alarm clock will have at least the following modes: Alarm on/off, sound on/off, light on/off.
Time will be displayed with NeoPixel devices
Project extras
Serial commands / debugging
Display light shows / demos instead of clock time
Code
Code is built with the Arduino core for an STM32F103C8 devboard, using the STM32duino tools.
FreeRTOS is used, with several tasks and semaphores.
Hardware
