Sending a wireless signal to a computer (with minimal data for identification)

[saltcellar9pdf]

let's say I have a room. In this room contains a computer that can be equipped with anything. This room contains to a lot of buttons (the buttons have infinite powersource)
I want to ( handle / read signal ) every button press on my computer. identify each button pressure separately.

My goal:
- Find the most cheapest & most quickest way to do this.

Ideas so far that seem to work:
- mongoose-os with ESP8266. (right now the best idea i think)
- PLC device for each button. (this is very overload!)

I want to find the simplest dumbest solution!
requirements:
- wireless
- be able to identify which button I pressed

Thanks in advance for your help

Hi,

It's rather vague information:
* what does "anything" mean?
* "infinite power" --> I'd sell it to become infinite rich
* a lot of buttons: 10? 1000? A million?

*****
A rather cheap, dumb and quick wireless solution:
* buy a wireless computer keyboard and use the existing keys ... or wire your keys instead/parallel to the existing keys

***
Questions:
* transmit edge detect (press/release) or level (ON/OFF)
* how many switches can be active at the same time?
* how many switches can switch state within a short (how short) time?
* how many switches can be wired to one trasmission unit?

...

There are so much parameters...
From "one active switch at one time" to 100 switch actions within 10ms...

I recommend you tell what you really want to build. A game? An industrial application?

Adapt these key loggers and use ESP32 or ESP8266 to act as a bridge
wirelessly to client box....
