This post is about showing how you can read a keypad and see what you just typed on it. I used a keypad as an input device and used one LCD that shows us what we just typed. We don't want to do any mathematics operation with keypad. All we want is just showing what we are typing. here is the codes in Codevision: https://drive.google.com/open?id=0B5WLZo9Cie21RGVvbzhSdHVaS1U here is the schematic in Proteus: https://drive.google.com/open?id=0B5WLZo9Cie21Y1hiR0lfOEtBV2s

This post is about creating simple string in 2*16 LCD that is a really popular code in AVR applications and you can use it as a part of your project. I  tried to show you the practical circuit too.                    here is the program in Codevision: https://drive.google.com/open?id=0B5WLZo9Cie21aHJBWmFHdXJTQ2c here is the schematic in Proteus : https://drive.google.com/open?id=0B5WLZo9Cie21aEUtMXFvZjRlWjg
