Keypad kpd = Keypad( makeKeymap(keys), rowPins, colPins, ROWS, COLS );
The above line works in arduino-0018, but not in arduino-0021.
In arduino-0021 it says that: 'Keypad' does not name type.
How would I fix that?
Can you show the whole code?
Maybe there is a library missing - Arduino Playground - KeypadTutorial - and - Arduino Playground - Keypad Library - as it is not installed by default.
Yep, that was it.
I had it in the old Arduino version, but not the new one. Thanks
