Electronic dice programming

hello everyone!

i working on making electronic dice, has 7 diode's in shape:

0            0               0
               0
0            0               0

with can make numbers dice has.
i got configured in such way press of button dice show next number:
example: dice shows 1 -> pushbutton -> 2.

i got 2nd button , want work this:

if press 2nd button, dice show number came before current one.
example: dice shows 5 -> pushbutton2 -> 4.

i'm using internal pull 2nd 1 , pull transistor 1st one. code:

code: [select]


//a program simulates real life dice.

//all leds attached board
int led = 2;
int led2 = 3;
int led3 = 4;
int led4 = 5;
int led5 = 6;
int led6 = 7;
int led7 = 8;
int btn = 9;
int btn2 = 10;


// setup routine runs once when press reset:
void setup() {               
  // initialize digital pin output.
  pinmode(led, output);     
  pinmode(led2, output);
  pinmode(led3, output);
  pinmode(led4, output);
  pinmode(led5, output);
  pinmode(led6, output);
  pinmode(led7, output);
  pinmode(btn, input); //button 1
  pinmode(btn2, input_pullup); //button 2
}

void clickthebutton() {  //button 1.
  while( digitalread( btn ) == low ) {}
  while( digitalread( btn ) == high ) {}
}


// loop routine runs on , on again forever:
void loop() {
   
    digitalwrite(led5, high);
    clickthebutton();
    digitalwrite(led5, low);
   
    digitalwrite(led, high);
    digitalwrite(led4, high);
   
    clickthebutton();
   
    digitalwrite(led, low);
    digitalwrite(led4, low);
   
    digitalwrite(led3, high);
    digitalwrite(led5, high);
    digitalwrite(led6, high);
   
    clickthebutton();
   
    digitalwrite(led3, low);
    digitalwrite(led5, low);
    digitalwrite(led6, low);
   
    digitalwrite(led3, high);
    digitalwrite(led6, high);
    digitalwrite(led4, high);
    digitalwrite(led, high); 
   
    clickthebutton();
    digitalwrite(led3, low);
    digitalwrite(led6, low);
    digitalwrite(led4,  low);
    digitalwrite(led, low);
   
    digitalwrite(led3, high);
    digitalwrite(led6, high);
    digitalwrite(led4, high);
    digitalwrite(led, high); 
    digitalwrite(led5, high);
   
    clickthebutton();
   
    digitalwrite(led5, low);
    digitalwrite(led3, low);
    digitalwrite(led6, low);
    digitalwrite(led4, low);
    digitalwrite(led, low);
   
    digitalwrite(led3, high);
    digitalwrite(led7, high);
    digitalwrite(led4, high);
    digitalwrite(led2, high); 
    digitalwrite(led, high);
    digitalwrite(led6, high);
   
    clickthebutton();
   
    digitalwrite(led, low);
    digitalwrite(led3, low);
    digitalwrite(led7, low);
    digitalwrite(led4,  low);
    digitalwrite(led6, low);
    digitalwrite(led2, low);
}
   

hi

is code posted working button1?
you using pull-up transistors? mean pull-up resistors?

if want dice display random numbers, don't need 2 buttons. need 1 button tell arduino when make new number.
and maybe easiest way use switch case.

you can learn switchcase here:
http://arduino.cc/en/tutorial/switchcase

and here project of arduino dice, produces random numbers, , used switchcase...

good luck!
