  • Hello all,
    I’ve just bought one keyPad for connect this to Arduino. Well, after having many problems, I have tested all the combinations with the pins, and i think that my KeyPad is not working properly, the problem is that my rows 1 and 2 doesn’t respond to no keys pressed.
    Have anyone had this type of problem.
    My tests with a continuity tester has been the folowing
    col 0 3
    col 1 1
    col 2 5
    row 0 2
    row 1 7
    row 2 6
    row 3 4
    I undestand that when a press the ‘4 key, I’ll have a closed circuit between 3 and 7 pins of keypad, doesn’t it.
    Can Help me anyone.

No public wish lists :(
