Educational2: using i/o (input-output) of a AVR microcontroller and configuring of alphanumeric LCDs

In this video we are going to learn about digital inputs in AVR microcontroller so you can add a key or an off/on sensor like micro switches to your MCU or your circuit. and learn how to config an alphanumeric LCD to your circuit. with an LCD you are able to design numbers of cool system and you can show your results.
more importantly you can design a clock and it's not soon....
with some very simple code, components and knowledge you can design your own clock....
there is 3 different coding about this concepts that you can find from this link:

so have fun and Good Luck...
