  • Keypad With Arduino Without Using Keypad library (First Tutorial)

    Hey Omar,I thought I'd include these pictures of the keypad I'm using so If anyone has the same keypad as mine then they can use these pictures here (that I modified from yours) as a guide to wire theirs up and it should work with your code. And your code also works on a nano without any modifacations...Thanks Againjessey

    Hi,Thanks for the code but I can't seem to get it working on my Arduino Nano. I would really appreciate some help to figure out what I'm doing wrong. I hooked up the keypad the same as it shows in your code using your pictures showing the rows and columns and corresponding pin numbers for the UNO. My Arduino Nano has the same pins as the Uno (digital pins 2 to 9 are the same) so I thought it would work without doing anything to the code. I guess maybe I was wrong about something I did? One thing I don't understand is that the 2 pictures you have of the keypad showing R4 to R1 and C4 to C1, the keypad looks backwards, I mean the button lay outs looks upside down and inside out and you show the ribbon cable coming out the opposite end to where they should be according to the ones they sel...see more »Hi,Thanks for the code but I can't seem to get it working on my Arduino Nano.

Any feed backwill be appreciated. Maybe I have my keypad wired wrong?Thanksjes
