Hello, I'm trying to modify this piece of code originally written for a nixie tube clock. The clock uses 4 nixie tubes to show hours & minutes but I wish to add 2 extra tubes to show the seconds as well. Can someone point me in the right direction as to which parts of the code to modify and some hints on how??

delay(1000);
a++;
if (a==10)

delay(2000);

}
}
From what I understand, after changing the "define numDigits" to 6 I then need to add a "narray" 4 & 5 here?
{
narray[0]=int(z/1000); // thousands value
z=z-(narray[0]*1000);
narray[1]=int(z/100); // hundreds value
z=z-(narray[1]*100);
narray[2]=int(z/10); // tens value
narray[3]=z-(narray[2]*10); // ones value
nixie.writeArray( narray, numDigits);
}
and then play with the "if" statement?
if (bcdToDec(hour)<1)
{
zzz=minute;
}
else if (bcdToDec(hour)>=1)
{
zzz=hour*100;
zzz=zzz+minute;
}
nixNum(zzz);
}
Thanks for any help at all
