Connecting Bluetooth HC-05 chips

Hi!

Is there a way to connect two HC-05 chips to be a slave and a master to have one chip have a button that lights an LED on the other chip. If so, would this be easy or hard because I am a beginner but I want to spend a month on this project so maybe I could learn along the way.

From what I know currently, I think syncing the chips might be easier than coding or am I incorrect.

Probably.

Do things one step at a time

Thanks for the repl!!!!!

Should I use two HC-05 or use one HC-05 and one HC-06

It doesn't matter. The point here is that you don't need two masters and HC-06 is a slave only. If you haven't bought anything, I suggest you get two HC-05s. By virtue of its greater command set, the HC-05 is more versatile and thus may be more use in the future. The price is about the same these days.
