Hello guys, i have made a 24x6 matrix, which shows the message “TEMP IS: (variable)” where variable is taken from sensor. The problem is this - around the digits there are lucent diods (here is a picture - http://postimg.org/image/qk3f78y7l/)
The code is in pdf.

Can anyone help me with this problem.

Why would you wrap a text file in a pdf? If you expect people to open your file, you will post it AS A TEXT FILE.
Why on earth did you post the code as a PDF? If you want any help, cut and paste your code as text between code tags as described in how to post code properly

I solved my problem, but i don’t understand why it happens.
When i removed “Space” from “tempArray” everything worked fine.

It is pointless to use a for loop when every iteration of the loop does something different.
Except that in every case, THE EXACT SAME THING HAPPENS. Your code needs some serious rework.
byte numArray [10][6] = {NUM0, NUM1, NUM2, NUM3, NUM4, NUM5, NUM6, NUM7, NUM8, NUM9};
byte newArray[100][6];
for (int b = 0; b < 8; b++)
{
newArray[a][b] = numArray[firstNum][b] ;
}
You seem to be using 8 elements from a 6 element array. That is seldom right.
