A very flexible RGB Alarm Clock written in Python3 using the transitions state machine.

Initially written for simulating a sunrise on a Raspberry Pi for a natural waking, the project has expanded into a very flexible state machine based alarm system with some nice features

• Unlimited RGB Alarms with day-of-week and repeat settings
• Customizable RGB profiles associated with each alarm. E.g. Sunrise, blink. Or write your own
• Pre-Cancel alarm previous night for one time only. E.g Want to sleep in for one day
• Speedup module for testing alarms and developing RGB profiles
• Each alarm is independently run with its own state machine

Hardware Setup

Pinout
Red Led = Pin 22
Green Led = Pin 18
Blue Led = Pin 17
Snooze Button = Pin 7 (Active Low)

Software Setup

Python3 is used for this project.

The following modules are needed

• Transitions (for state machine, github)
• PyQt5 (for graphical output, optional)
• RPi.GPIO (for input button)
• pytz (for timezone)
• pprint (for text display)
• pi-blaster (for PWM of Pins)
  ... and others

Steps to get software up and running

• Clone this repository
• Update alarms_db.tsv. Details are within the file itself
• Use existing RGB profile or write your own profiles. (Sorry the profiles are a little complex. However, the profiles are very flexible and potential disco lights could be made)
• Run screen/tmux since the scripts dump text on screen showing alarm(s) state
• Run sunrise_alarm.py (python3)

Coming Sooner(or later), aka Roadmap:

• Sound capability
• RESTful API for web control
• Modify alarms from Android App (based on RESTful)
• Qt5 based RGB Alarm Profile maker. Build profiles visually instead of coding
