AVR Peripheral Exercises

8x2 LCD display and 4x4 Keypad were connected over an Arduino. This is an Arduino program that verifies if a user entered the correct Pin. There are only 3 attempts after which will have to wait for 10 mins to re-enter the password.

This implementation allows reading a 4x4 keypad without an external IC encoder (like the 74C922/23). It performs the same function as the IC, but in a simpler form. The module can be used in various projects, such as a calculator. A detailed explanation is provided in the README file.
