This is a Rasbperry Pi-based doorbell.

It sets up a service to 'listen' for an input on GPIO pin 23.

The circuit should be connected on GPIO 23 and ground on the RPi.

When the circuit is closed, it triggers a script that plays an audio file.

This is written for a Raspberry Pi Zero W with an Adafruit I2S DAC bonnet.

To add:

• incorporate links to components, libraries
• steps for setting up service
• steps for adding audio file
• add script to randomise audio files
• using omxplayer to play audio file
• links to lights
• integration with other tools within network for broader notifications
