A Google Paper Signals-inspired notification system written in Python and Arduino C.

According to Wikipedia:

Andon (Japanese: アンドン or あんどん or 行灯) is a manufacturing term referring to a system to notify management, maintenance, and other workers of a quality or process problem. The centerpiece is a device incorporating signal lights to indicate which workstation has the problem.

andon is a combination of two projects:

1. ``nodemcu_client``: This is the client-side, to be installed on a NodeMCU Chip. 
2. ``andon_webserver``: The server side is to be installed on a Linux machine of your choice, preferably a Raspberry Pi (any flavour should do).

andon hopes to be similar, in spirit, to the Google Paper Signals project, but a little more powerful in what it can do.

* Voice integration, using ``voicehat`` and ``google_speech``.
* Chat integration, similar to ``google assistant``, but over a rest api, 
to be accessed via a browser. I'm going to use ``Flask``, ``Bulma.io`` and ``ES6`` for this.

* Rest API, coded in ``arduino c``.
