I am trying to figure out what to buy for development and display purpose. In particular my aim is to have a display (and perhaps some sort of controller?), which just displays some static label. Once it receives an update somehow, it should refresh.
Ideally I want a display (and a controller), which would process Bluetooth or Wifi signals (from e.g. a nearby smartphone) and update the displayed contents.
My question: in order to achieve this, what do I need for the display to work and receive signals via Bluetooth or Wifi? And what do I need in addition to this for development?
Does the display need an Arduino or Raspberry Pi to run?
I am pretty savvy in regards to software, but I have no idea about the required hardware...
