UNO: Sd + LCD + 4x4 Keypad + others

PaulS:

but I am afraid the libraries will use the same pins

The LCD and keypad use the pins that you specify. The SD card needs specific pins (the SPI pins).

Thanks a lot Paul, I just found a way to read the keypad with a single analog input, https://www.youtube.com/watch?v=URO042VrCKU PRETTY COOL!
