Hello people,

I am doing a school assignment on LED memory game. Example:

Led 1 light up, the person has to enter A for the answer.

The part that I don't know how to make is this.

When Led1 follow by Led3 follow by Led3 light up, the person has to type in A follow by C then C. I don't know how to make the program telling the person is incorrect if the person press A then B and finally C which is wrong for the second answer.

Can someone enlighten me with guide site? Or anything?

thank you.
