Connect those wires: Pin - push - GND

I'm using the Arduino Mega with the A11, A12 and A13 pin and it has worked flawlessly, not to function may have a fault on the board. Seeks to create a simple program just to test the pins.
The other system with the resistances, I'm not using now, but I've also tested it before and it worked.
Eu estou a utilizar o arduino mega com os pinos A11, A12 e A13 e tem funcionado sem falhas, para não lhe funcionar pode ter alguma avaria na placa. Procure criar um programa simples só para testar os pinos.
O outro sistema com as resistencias, não o estou a utilizar agora, mas já testei antes e tambem funcionou.
