Keypad.h not recognized?

my arduino sketch doesnt have keypad.h recoginized, do i need to download it or what can i do?

Arduino: 1.8.13 (Windows 10), Board: "Arduino Uno"





















keypad:1:10: fatal error: Keypad.h: No such file or directory

 #include <Keypad.h>

          ^~~~~~~~~~

compilation terminated.

exit status 1

Keypad.h: No such file or directory



This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

Hello, which board are you trying to use? Only certain boards work with keyboard.h.

edit: I see you are using an arduino uno, that board will not work because it does not have native usb. You have to have a board that has native usb to use that library.

Yeah I finally realized I needed to install a keypad in my library… rookie mistake lol

Yep, “Keypad.h” is a very commonly used, but not bullt-in, library.
