Ahh you are correct, i just assumed that you knew what it was that i was trying to do.
the easiest way to explain it is to show a picture, which i have attached.
i know that the parts needed are fairly easy to put together. the long and the sort of how i will be using the arduino is it will control all of the physical sensors.
one laser when activated will shine onto a photosensor, which when broken will indicate that it has indeed been "broken" . this will also control the power to the laser through a low voltage relay. as the minute it is broken i want the laser to turn off for a set amount of time (5-10 seconds for protection).
basically i will repeat this scenario for as many laser clusters as i need.
before a player joins the game they will be able to choose their difficulty. (easy,medium,hard, extreme) which they will need to choose before they enter. basically easy will be one set of lasers, medium will contain all of the easy lasers plus add another set, and so on and so forth.
the player will also be able to choose how many players it will be upwards of 4 players per game. or a solo game. so this will be another selection they will have to make. there will be 4 buttons at the beginning for multi player. a solo game will consist of 4 colored buttons that have to be pressed in a sequence. same as the other players. each payer will have to hit their buttons to be able to move on to the next button.
this will naturally be a timed event. so i would like a leader board, as well as how many lasers have been tripped.
im in the process right now of doing up a flowchart on how it will all work if that will be beneficial i will upload it as soon as i am finished
