Alarmpy

Alarm clock written in Python mainly targeted to Raspberry Pi

Requiremens

• Flask
• ffmpeg(ffplay)
• RPi.GPIO [optional]
• cec-utils [optional]

Components

• Web frontend written in Javascript using jQuery for AJAX calls and DOM manipulation
• Bulma CSS
• Web backend written in Python using Flask
• Alarm clock written in Python

Frontend

• 100% AJAX
• Lists set alarms
  

Backend

• Return and change alarm info from/to local JSON file that keeps the alarms

Setup:

• Clone the repo into your Pi and run alarm_clock.py as root(GPIO requires it).
• Access the web server at http://[IP ADDR OF PI]:5000
  Flask setup:
  export FLASK_APP=server.py
flask run --host="0.0.0.0"

Alarm clock

• Terminal frontend
• Uses ffplay for alarm sound file playback

Pi

In series: GPIO port 2 -> 10k ohm resistor -> button switch -> 3.3 V
Press button for ~1 second and the alarm will dismiss. If TV supports CEC and cec-utils is installed, TV will turn on before the alarm rings and will return to standby after alarm is dismissed(therefore external loudspeakers are not required).

TODO

• Raspberry Pi GPIO
• Clean up terminal interface
• Auto IP address(must be configured in source ATM)
• LED Ambient light
