Hi everyone, an arduino newbie over here. I have problem to get a library and tutorial to connect my keypad, LCD Display and arduino. Im using arduino Mega and a 12 button keypad .Could anyone please tell me the type or code of the keypad or any tutorial and library that I can use to connect the three things (Arduino, keypad and LCD display)? I have attached the links of the components below .Thank you .

I don't understand what you mean. You don't connect the LCD and Keypad together. You connect both to the Mega. There are plenty of pins available. Just change the pins to the ones that you use.

I  can connect the key pad with arduino and i can connect the lcd with arduino separately but i cant seem to merge the link between the keypad and lcd together ,as my program required me to set some settings by  pressing buttons on the keypad and making the value appear on the lcd .

I think you are getting slowly to the point. You are not asking how to simply connect lcd and keypad to your mega, but how to get your mega a user inteface to input numbers. Is that right? Try to be more specific how exactly you want to iniput what. Someone may have some code for you.

There might even be some tutorial for that. I have not made any myself but you are welcome to try out my sample codes.

look for phi_interfaces library on arduino playgrounds. I'm on ipad now, no way to easily get you a link.
