hello everybody i have a project that is a bingo


Hello everybody I have a project that is a bingo board run by laser pointers, light sensors, and leds. Basically I''m creating a 5 by 5 grid (bingo board) in which each row and column has a laser pointer which shoots a laser to the other side of the grid to a light sensor. Basically when someone interrupts a pair of sensors (a column and row) that spot will light up. I''m really confused with the hardware part. I''ve always been a software guy and just don''t have a clue on how to get started. I''m trying to right now make a 2 by 2 prototype to show how this will actually work. The problem is I don''t know how to create the hardware for the prototype. I need something to hold down the lasers and shoot straight instead of them moving around and shooting diagonal. I''m also confused on how to make the final hardware but I''m more worried about getting the 2 by 2 done first. Any help will be appreciated. Thank you guys.
