When I press a button on the Keypad, the number (go HIGH). However, when I release the button, the number does not go back to its original state. I need to control an instance where when I select a number a certain section of the code will be active. I then need to change values in steps, 1 per push of the button, which mean the buttons needs to return to its original state after I release it. How do I get that to happen.
I am using a 4x4 keypad with a Arduino.
I wonder how you're trying to accomplish this (the sketch, which library, etc.).
Have you considered the possibility that your wiring may be a bit off in some regard?
