python3 main.py --help

A default tune is included with the project. Additional tunes can be configured by creating a file and loading it with the --tune argument.

A tune file contains lines with float values on each line. Each value represents a duration for either a buzzer sound or a sleep. The first line is a sound duration, the second is a sleep duration, and so on.

If running with default settings, the program can be easily launched with:

./launch.sh

Manual execution can be achieved with:

python3 main.py
