GOAL: to make a wireless nintendo switch controller
First steps, i want to be able to connect a keyboard to the Pi3 to use as a wireless keyboard ie. can connect to another computer or device and use as a regular keyboard. So connect keyboard to Pi3, then Pi3 wirelessly sends keyboard signals to computer. And was wondering how i could do that.
Then i want to be able to instead of a computer, send that signal to a switch instead and use it as a controller. i dont know how to do that either. Ideally i want to make my Pi3 into an adapter that connects through bluetooth to my switch. Or alternatively i could buy an bluetooth adapter to plug into my switch(unsure if this is how it works, or what adapter to get).
I saw some dude use his electric drum kit as a switch controller while playing super smash brothers which was what inspired me. So if anyone knows how to do this or has any resources(things i could read) that could help me do this that would be awesome. I have very limited knowledge on computer systems as i have just started learning about it so i'm unsure about how possible this project is and haven't found much online about this either.
