Arduino - tutorijali, pitanja, primjeri i projekti

[Makso]

Da li mi neko može pomoći kako da prepravim ovaj kod, trebalo bi da počne sam brojati čim se Arduino upali ili na uslov tastera, kada se taster pritisne (momentary) počinje brojanje a drugi put pauza?

Da ne moram unositi broj u serialu, nego samo da krene da broji od 0.

Code:

int aPin = 2;  //         A
int bPin = 3;  //      ________
int cPin = 4;  //     |        |
int dPin = 5;  //   F |        |  B
int ePin = 6;  //     |    G   |
int fPin = 7;  //     |________|
int gPin = 8;  //     |        |
int GND1 = 9;  //     |        |
int GND2 = 10; //   E |        |   C
int GND3 = 11; //     |________|
int GND4 = 12; //        
int num;       //         D
int dig1;
int dig2 = 0;
int dig3 = 0;
int dig4 = 0;
int DTime = 4;

if (Serial.available() > 0)
{

 Serial.println(num);

 num = num - (dig1 * 1000);
 dig2 = num / 100;
 num = num - (dig2 * 100);
