“Read the time at night? Without glasses? Impossible? Focus on 2 light points, which will tell you the hour and the minute. Sleeping drunk with drowsy eyes, reading the time on the clock becomes difficult. Glasses not handy or slightly drunk from the last party? There is an Adafruit NeoPixel Ring with 12 LEDs which can be individually controlled. By symbolizing the hour as a red LED and the grouping of the minutes into a 5 minute range as a blue LED, you can estimate with only one NeoPixel Ring how much time you can spend in the bed until the alarm rings (this can be retrofitted with a buzzer).”
