Switch buttons as a Keyboard?

Projects Programming
1

Well, I'd like to make like a arcade joystick (Just from now, the buttons, not the joystick). But I'm still noob on this. So, um...
The thing I want to make is for example:

When I press the Switch Button on the pin 13, make it press like the A key. (there will be only 3 buttons, so, the buttons only will be A, B, and C.

So, is there anyway to do this with an Arduino Uno? I mean, with programming?

Thanks for the replies and for the help.

Yes you can.

You can assign each button a different pin, or you can use one pin for all buttons but you need to separate each button with a different resistor value.

It's possible with certain Unos (must have a ATmega16U2 as the USB-serial chip) but it's very complicated. You are much better off buying a Pro Micro or Leonardo which makes it very easy to do keyboard emulation using the Keyboard library:

Or use a USB shield on a uno
