The alarm-clock-light is simulating a sunrise to make us wake up more gently than having a horrible sounding alarm blowing your brains out each and every morning!
It’s based on the Arduino MKR1000 and has a web-interface for setting the alarm. It has got an LCD to display the date, current time and alarm-time. Moreover, it is showing the percentage of current brightness of the light (LEDs).
