The weasly clock implementation
For this to work you need to create a fifo named: servofifo.pipe
Its built using Adafruit's servo shield.
Also - mpg123 should be installed and there should be a config file for Alsa specifying which audio device the gongs should be played through.
A simple config is: defaults.pcm.card 1 defaults.ctl.card 1
Where 1 is the number you see for the output in: aplay -l
For config tools install: sudo apt install alsa-utils
