My project is a bit different than any I have found here.
My plan is to use an RF Switch (433mhz) to simulate a keyboard press on the computer (numbers 0-9)
So far I have built a RF receiver with a Mega and 433mhz receiver that helped me decode the RF signal.
Now I'm hoping somehow to hook up a 433mhz receiver to an Arduino Pro micro which will translate the RF codes into a keyboard press - but I'm pretty lost on how to do that!
Any tips or advice on what I would need?
Thanks in advance!
How will you handle RX packet collisions?
I'm really only starting with numbers 1-4 and didn't know if this would be a big issue?
Again..total newbie!
Whilst using Wireless for quiz type buttons sounds easy, the reality is different.
Wireless communications is never going to be 100% reliable. You need a system that can work when the button press is sent but not received due to inteference etc. In addition you need to deal with the situation where the button press is sent from all the buttons at the same time.
Not so easy.
Not so easy but gotta be do-able!
I’m not concerned about any two buttons being pressed at the same time as it will only be a choice for one game.
Using RC and Keyboard libraries maybe an if Rc received then a keyboard write command or something

I find it hard to reconcile that with your Title.
Most times "wireless quiz buttons" refers to the buttons that 3 or 4 (or more) quiz contestants have so that the computer can figure out which person pressed their button first.
I think that is the understanding that gave rise to the comments in Replies #1 and #3.
If all you want to do is have one person press one of several buttons to send a message to a PC then that (to my mind) has nothing to do with a quiz and should be quite straightforward - unless the person accidentally presses 2 buttons at the same time.
What exactly are you trying to create ?

I have a Quiz program that one person plays at a time. The answers options are keyboard presses 1, 2, 3 or 4.
So I'm trying to build wireless buttons for that.

You said in your Original Post "So far I have built a RF receiver with a Mega and 433mhz receiver that helped me decode the RF signal."
That sounds like a good starting point but it is not clear exactly what you have got that sends the RF signal. It would be a good idea if you post the working program and a link to the datasheet for the device that is sending the codes.

I've actually solved this and have it working now. If anyone needs assistance in doing the same, let me know.
Good to hear you have a solution
If you post a description about how you solved it - details of the actual hardware and the program - it will help others.
