The clock features:
- Alarms are flexible and programmable. Alarms can be configured to override other alarms, run on specific days of the week, or only in a particular date range.
- A countdown timer displaying the amount of time until the next alarm sounds.
- Motion sensor, which can cancel an alarm, and also when triggered, lights a string of colorful LED's under the edge of the bed, providing a night-light when needed.
- Separate button module, which can be conveniently placed away from the display unit.
- Ceiling projection of the time, date, weather, upcoming alarm details.
- Ring sounds can be a buzzer, sound or music file, midi file, or an internet radio station.
- It can also play internet radio stations, or sound files when desired.
- A companion app to configure and program the alarms.
I built it using a Raspberry Pi W, Arduino Leonardo pro-micro, bits and pieces from Ebay, and some found & recycled parts. I also wrote lots of software for the Arduino, companion app and system software.
I can easily add other features now, such as turning on wifi-controlled lights and switches, sending messages, etc. No plans to though. Yes, there are a lot of cables!
