Badminton Scoreboard Build

[pradoartz]

Hi,
I am building a scoreboard for my friend's badminton court. So i am planning of using Arduino Uno as the projects brain. I found a working code in internet, which is as follows.

Code
[mod edit: placed code within CODE tags to improve readability]

// Button Inputs
const int p1IncPIN=5, p1DecPIN=6, p2IncPIN=7, p2DecPIN=8;
// variable for reading the button status
int p1IncButton=0, p1DecButton=0, p2IncButton=0, p2DecButton=0;
// Video Outputs and Video Data
const int ledClockPIN=10; // to pin 10 on J1 (CLK_IN)
const int ledDataPIN=9;   // to pin 9 on J1 (DATA_IN)
const int ledLatchPIN=3;  // to pin 7 on J1 (DIMM_IN)
// Display Digit HEX Code {0-9} for Sure Electronics 12v 2-Panel 7-Segment Board
static byte displayDigit[10] = {
    0x3f, // 0
    0x06, // 1
    0x5b, // 2
    0x4f, // 3
    0x66, // 4
    0x6d, // 5
    0x7d, // 6
    0x07, // 7
    0x7f, // 8
    0x6f  // 9
  };
//set hex variable initial value
int p2_Ones=0, p2_Tens=0, p1_Ones=0, p1_Tens=0;
// set the variables for the score
int player1Score = 0, player2Score = 0;

Question:

I can't find any schematic for this project, anyone please design me a circuit. Thanks in advance.

 

[Harald Kapp]

When you follow the link from youtube to the arduino forum's entry for this project, you'll find teh schematic in post #6.
The first information on tha thread is that he's

Using the SURE Electronics 2.3" 2 Digit 7-Segment LED Display Board (DE-DP22811). It is being powered by the test board that comes with the 4 Digit board.

Where did you get the type face? It is smaller than the standard used here but I find it much more readable.
Thank you

Times New Roman? Have you noticed the font select button in th etop row of a post (#6 from left)?
