Hi I have a project for an interactive display where there are 5 buttons which are answers to questions. If the questions are answered in the correct order then an output should go high but if they are answered in the wrong order a different output should go high. Could somebody give me some direction on how to achieve this? I understand how to turn an output on if an input is triggered it's getting the board to determine the order the inputs were triggered that I'm struggling with.
I've programmed this on a PLC which works well but is an expensive way or doing things and it seems to me that the Arduino is perfect for this application.
Any help would be much appreciated.
