Hi diego
i have taken an Arduino Mega 2560.It works fine.
But i could not compile the 4x16 ino file from source, there is an error while compiling.
I have changed the Lines
//initialize an instance of class NewKeypad
/Keypad customKeypad = Keypad( makeKeymap(Keys), rowPins, colPins, ROWS, COLS);
/
to
//initialize an instance of class NewKeypad
/Keypad customKeypad = Keypad( makeKeymap(Keys), rowPins, colPins, ROWS, COLS); /
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
Hi all
is there a way to connect an arduinno uno with a 4x16 Matrix
my old board was 8x8 now i have 4 cables more
thanks
chrigu
Hi,
For the Arduino UNO, you have :
A0-A1-A2-A3-A4-A5 = 6
and:
0-1-2-3-4-5-6-7-8-9-10-11-12-13 = 14
Should be enough in/out
Check very well which is entry and which is out and don't forget to change the program of the arduino (making the right nuber of columns and lines)

Hi diego
0 is RX and 1 is TX can i use them also?
cheers

I think it gonna be fine, check:
https://www.arduino.cc/en/Main/arduinoBoardUno
it is written:
"It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs"

For using PIN 0 and 1 (D0 D1) you have to set in Setup:
UCSR0B = 0;
I have not tested it yet, but it schuld work.
