So I want to make a scoreboard using the Arduino Uno (I have 2 if necessary) and 2 lcd screen. I'm a very amateur programer and want to know how to go about doing this cause there isn't anything online. Basically I want the ball to trigger some kind of sensor and count one point on the lcd screen of the scorer and I want the scoring to have no limit and only stop when you press the reset button.
lcd screen I'm using ==> http://www.ebay.com/itm/like/360730910251?lpid=82
I would love some help and I would love to have it score automatically but if that is to difficult a simple pushbutton counter would be fin and I don't know how to do that either.

... cause there isn't anything online....
True. There is nothing online on "foosball scorer point counter with LCD " with readymade code and finished circuit diagrams and BOM (Bill Of Materials)
On the other hand there is gazillions of pages on how to interface an LCD to the Arduino, How to call the LCD library to write any text, How to connect a push button to the Arduino, How to read a pushbutton (debounce), How to use a photogate / photocell / lightbeam with the Arduino ....
I'll even give you the code for incrementing a counter - forever 
Score = Score + 1 ;
When you have made some of your project and have a specific problem you can ask again, and I am sure somebody will help. But at the mement the question you ask is too vauge and open ended. I suggest you start with getting the Serial.print to show how often you push the button. Then add the LCD. Then replace the button with some lightsensor. Small steps, getting something to work as the project evolves.
