I need to develop a project with Arduino UNO. I have 44 keypad and 162 LCD.
I want to display different characters when different digits of keypad are entered.
at start it will display “Enter Code” - (Line 1)
It will display the entered Code in line 1 like (Enter Code 1234)
Then Press A to confirm.
1234 - ABCD
1111 - PQRS
1212 - RSTU
If 1234 is entered, it will display ABCD on line 2. like this it will show different characters on display with different codes.
If any different value other than the list is entered - it will display -
“Wrong Code” (Line-1)
“Press B button to reset.” (Line-2)
Please guide me.
