This is a revision of the code used for Screaming Cauldrons and A Very Merry CircuitPython Christmas projects.

This version will allow you to use a single Trinket M0 to handle the inputs from 4 Sharp Proximity sensors. The limitation is that you will now only be able to trigger a single pin on the Audio FX board. This is purely because there are only 5 available pins on the Trinket M0. Other CircuitPython boards may offer more pins but have not been tested with this script.

This version also adds a discrete speaker Class D amplifier.
