Thanks, for quick replay!
I just need to connect my keypad to work properly
I have already identified my keypad cols and rows pins, but I don't know, where to put resistors while connecting keypad to my arduino. I want to connect each pin of the rows and each pin of the columns to arduino. So, where I have to connect resistors?
it is said, that I will need resistors 2k to 10k, on each of the row pins. So, how to do this? this resistors should be between wire whitch is coming from keypad to arduino or that resistors should be on ground pin?
