The problem comes when I want to connect them because the push button pins are too small to fit on the female part of the wire (the other part it's connected to arduino).
I started soldering some wires to the switches this morning, but it was a bit difficult because there is a very small contact between the wire and the button. Paul, if those aren't the correct switches to make a keyboard which ones will be better??Thank you for your answers
Hello Paul, I'm working on a enigma replica(the German encryption machine of WWII). I'm building it only for fun and research, because when I have finished it I will improve it a little bit, and in a future I will connect to a server and talk with my friends within this machine and its encrypted messages. Discussing about the size, I don't have any preferences, not too big or too small, more or less like a normal keyboard. Thank you for your attention.
