On the shortest day of the year wouldn’t it be nice to wake up to a bright room? This alarm clock with an integrated wake-up light is one way to do just that. It has some nice features, like a wood veneer that allows the seven-segment display to shine through, but hides it when the display is turned off. There’s also a feature to adjust the color based on ambient room temperature (another way to dwell on how cold it is in your bedroom).
A CC1101 RF chip came to the party, but we can’t figure out what it’s purpose is in this circuit. If you can shed some light on its involvement please do so in the comments.
