What is the Industrial Fidget Controller?

The industrial fidget controller (IFC) was originally conceived as a joke (fidget spinners were a fad in 2017 at Hacklab 2.0, but was crowdfunded by members to become a reality.
The intent was design an industrial control panel with an assortment of 22mm industrial buttons, indicators, and other tactile elements as a fidget toy for visitors.

Each switch on the front panel, as well as remote devices (through connectors J1 thru J4) are exposed to Home Assistant using a MODBUS TCP integration to poll the PLC at a 5 second interval.
- Note: polling frequency is limited by Home Assistant due to stability issues with the MODBUS TCP plugin. The PLC can support a much higher polling frequency.
Certain button or switch combinations can create light animations as a reward for fidgeting. More Easter eggs may be added as time progresses.
Inside the enclosure an electro-mechanical counter keeps track of the total number of button pushes this installation serves to satisfied customers. If you are quiet, the electro-mechanical counter can be audibly heard.
There are 2x remote keystations, each featuring a key-switch, a toggle switch, and a future LED back-light for the switch.

Entities are exposed to Home Assistant based on the switch contact or LED indicator corresponding to the location below.
All entities are prefaced with IFC_* where * is the device address (eg: A1, B2, etc).
Push buttons B1, B2, C1, C2, C3, D2, D3 have been configured as latching switches and can be used to enable or disable specific Home Assistant output devices (eg: a disco ball).
Circuit breakers A1 + A4-A8 are configured like any other input device to the PLC and do not involve any mains AC voltage (the entire front-panel is powered by +24VDC and is grounded for safety regardless).

Note: J1-J4 are NOT hot-pluggable. Please power down the unit before disconnecting these.
