(Probably not the best/right place to ask, but.....)
I'm stuck with which way to go:
I have NR running on my RPI and it is coping with it, but it is headless and is the "brains" to the system.
I need a display system.
The question is which way to go.
Do I get another RPI (I don't want to overload this one) and connect a display (like: display)
Or do I go with an Arduino MEGA?
It has many outputs to drive LEDs (Neo-pixel probably - though with those you only really need one pin) and other things.
It has buckets of memory so it can listen to my MQTT topics and act on them.
I also believe I can attach a display to it too.
Though looking at the link above, $14 with a free RPI 3 is tempting!
(Ok I'll take that back. Read the "terms and conditions". Should have known better.)
I am still not sure about RPI GPIO for things like buttons to acknowledge notifications, etc.
The arduino I/O is a bit "easier" at this stage.
Has anyone done anything like this and has any tips for a new person?
