4*4 keypad and 16*2 LCD

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.

Keypad display

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.

Hi, Welcome to the forum.

Please read the first post in any forum entitled how to use this forum. http://forum.arduino.cc/index.php/topic,148850.0.html then look down to item #7 about how to post your code. It will be formatted in a scrolling window that makes it easier to read.

Can you tell us your electronics, programming, Arduino, hardware experience?

Is this a school/college project?

Thanks.. Tom.. :)

Dear Tom,

this is a school project. I have no experience. It is requested by a child who is in 6th class- 12 years old. See if you can help else Thanks....
