Hello, I would like to be able to use the current keypad library here but be able to enter 3 keys. The current code only recognizes one key with one variable for that key. I need three keys recognized and three variables for those keys i.e. keyA, keyB, keyC. Does anyone know how to do this? Does my explanation make sense? Thank you.
Example: Currently, if I pressed 1,2 and 3 on the keypad the variable "key" would only be equal to 3.
I would like to be able to enter 1,2,3, and 4 on the keypad and have Serial.print show 234 with variable "keyA" = 2, "keyB" = 3 and "keyC" = 4.
