Description

So I'm making 2 keys arduino keypad. 2 legs of resistors of each key goes to 2, 5 and 6, 9, output cables are going to 5 and 9.
I have problem with capacity, it goes really high and it's mixed with corect values.

Errors or Incorrect Output

Serial monitor goes like:
1, 20
1, 4000
1, 20
1, 15
1, 4000

There should not be those 4000, big values.
