Hi,
I'm very new to Arduino, having worked through some of the starter projects over the last few weeks I set about making my first Arduino project of my own, a very simple keypad code entry system which will turn on an LED when the correct code is entered.
It uses 5 pushbuttons each with a dedicated LED to indicate whether these buttons are in the OFF or ON state at any time. By getting the correct combination of OFF and ON buttons the main LED lights up. The combination can by changed to whatever you want it to be, instructions for this are in the code.
This project was put together by building on the starter projects so some of the same code from those projects is present here.
If anyone has any ideas for improvements or interesting things to do with this project then I'd be happy to hear them.
