LCD and 5 switches

I'm new to this exciting game.

The first project I'm messing around with requires an LCD and 5 switches.

I got the LCD up and running quickly thanks to the info available on the net. I then managed to add a switch.

I tried to move on to 5 switches, this is where I got stuck.

I've read about using multiple resistors to plug multiple switches into one analogue input but I've got available digital inputs I could use (would the digital inputs be the best and easiest way?).

If anyone recommend a method it would be much appreciated.

It would be the least ambiguous way, and would need the fewest (zero) external components.

Thanks for the quick reply.

I'll have a bit more of a fiddle around. The setup I just tried with one switch, when pressed resets the board. I'm impressed with my skills.

Could somebody point me in the right direction for wiring switches without resistors?

I looked at this:

but I must have gone wrong somewhere (it resets the whole thing when I press the switch).
