Arduino - Table football score counter

[Hohenheim]

The project was born as a table football score counter.
It was my first project and it's very simple.

Clicking on one of the two buttons you increment a variable for the score of each team. By the difference from the two values the software print on an lcd messages like: Reds takes the lid, or OMG It's over 9000! or I don't know, whatever you want. Then during the play you can se the two scores printed on screen. If you want you can also use a flex sensor to automatically increment the variable when taking a point.
You can also create a cycle to get a game with only 10 balls.
You reset the values reinitializing arduino pushing the reset button.


There are two buttons connected with the pin 2 and 3 of arduino.
The lcd is connected as follow:
16 LED-  to Gnd
15 LED+ to 5V
14-11 DB 7-4 to 12, 11, 10, 9
10-7 Unused
6 E to 8
5 R/W to Gnd (unused)
4 RS to 7
3 V0 to a 10K ohm potentiometer
2 VDD to 5V
1 VSS to Gnd




Here the code (I'm sorry but messages are in italian... Really, I don't know how to translate them XD)
