hello all, i hope this question has not been asked already, i did a couple searches and did not find anything.
i'm wanting to code the 4x4 keypad to read a 6 number code then activate my RFID card reader. i have the keypad up and running but what im stuck on is how to store the 6 numbers then do a lookup to a table of authorized codes. thank you so much for any help so far everyone on these boards has been an incredible asset in to my learning experience! thank you again

    Do you mean like entering a password? If so, use our Google search engine to find the thread on keypads and passwords. It included some example code. Let me see if I can find it real quick…I think this is it.
