Reading a sequence of digital inputs -> take action based on sequence

Using Arduino Programming Questions
1

Hi All,

Newbie to Arduino language and worked out a lot of things reading this forum and following tutorials/books but now I am trying to read a sequence from three digital inputs (switches basically). If the sequence is correct I want to put another digital pin to output HIGH. If it's not I want a led to turn on.

I have trouble looking in the right direction.. would I need to use an array for this? Or a string?

If the sequence is fixed in the code then all you need is if/else.

But perhaps there's more to it than you've said so far?

What do you mean by "sequence"? Are you suggesting that the order that pins go HIGH (or LOW) is important?
