Schroedingers_Kater:
So, you are suggesting I use two other arduinos to communicate with my Pro Micro?
I am a bit confused. Your diagram was not there when I replied and I don't know if you have made other changes to your Original Post. For the future don't make changes to existing posts other than to correct typos. Put new information in a new Reply.
I had assumed you wanted to replace the wired connection between the Pro-Micro and the PC and I was saying that that would not be easy.
And I was suggesting that you leave the Pro-Micro connected to the PC using the USB cable and create a wireless link between it and another Arduino. I did not interpret the original version of your Original Post to mean that you wanted multiple wireless links.
Of course there is no reason why you cannot have multiple Arduinos with wireless links to a Pro-Micro connected to your PC. The cheap and effective nRF24L01+ modules are one way to do that. Have a look at this Simple nRF24L01+ Tutorial
