Hi, Im returning to this after a 5yr break, so still very new. Ive tried to search some libraries
for the code to input key stroke or preferably a 4 figure code from a keypad without success. Does
anyone have any suggestions on best place or way to find the code to do it. I cant believe its not been done. Thanks in advance

If you mean like a password, I recall looking at this keypad example in the playground but can't recall if I ever used it. So I'm not vouching for it, just giving you the link :wink:

Might help if we knew which keypad.

For 3x4 and 4x4 matrix keypads there is the Keypad library.

Google "input multiple digits keypad Arduino" for some posts on that subject.

As mentioned @bygroundFungus, That is what you need to do. If you need more detail, you can see this tutorial
