my first post.
i’m quite new to arduino, going to order a kit in the next few days.
i’m addicted to table soccer, like the garlando deluxe
i already “modded” it to have some LED lights from IKEA.
however, i wanted to go a little bit more crazy
i’m planing to make a little intel atom server inside the table, that has a PHP/MySQL Server, controlled with a Mimo USB Touchscreen, and using some Arduino technology for some fancy LED stuff.
after each goal, the player presses some buttons near the handle, telling the system which figur shot the goal. this gets registred in a database along with several other datas, like player name, time since last goal, etc. at the end, i can make statistics about who scored best, shot most with with figur, etc.
so far, this is all done with flash and the Server for logging.
now, where does arduino comes in?
well, for displaying the Score with two 7-Segment displays, and maybe two LED bars with each 6 LEDs (official rules for garlando only counts to 6 goals, not to ten).
as i’ve read, there is a library for “talking” to 7 Segment displays using the Max 7221/7219.
thats seems quite good, and i think i could programm it that way.
however, is it possible to launch a Arduino Programm at system start up without any interaction?
as said, when i power that computer, the flash front-end is set to autostart, as is the server. but i also need the arduino application to start at systemboot.
i’ll be using Mac OS X or Windows (tried linux, but its too uncomfty for me)
further, i didnt found a shop in switzerland where i could buy eighter MAX7221 or MAX7219.
is it safe to buy that chip from ebay?
and what exactly are the differences between those two at all?
