Hello
I have a problem with 4x4 keypad library. I download the library from this link:
http://playground.arduino.cc/code/keypad#Download
I think is the official website of arduino for downloading libraries. After finish downloading the library i move it in the libraries folder on arduino's folder like the link says.
When i want to add the library by writing #include<Keypad.h>the program doesn't recognize it because the Keypad word doesn't turn to orange. And if i add the library from sketch->add library doesn't appear on the screen too. I'm using the 1.0.5 version.
Thanks
