Hello, I have a long experience in Hardware and Software product design. I have used Atmel Controllers and Arduinos in multiple projects. I have used keypads and LCD panels in past projects. From my understanding, the hardware is already wired and you need only the software that runs on the Atmega, right? Please let me know... Thanks Vinod
