Today Joe tried to light the rest of the letter A in class by adding more code to what was already there this is how our code looks right now:

int an[] = {11,12,13,11,12,13,10,13,10,12,10,11,10,9,9,11,12,9,8,11,8,10,8,9,8,7,9,7,10,7,7,11,12,7,13,7};
int ca[] = {12,11,11,13,13,12,13,10,12,10,11,10,9,10,11,9,9,12,11,8,10,8,9,8,7,8,7,9,7,10,11,7,7,12,7,13};
int array [6][6]=

 I couldn't understand why only the last two rows for the letter "A" were lighting up instead of the entire letter as well as why the delay is not short enough to make it look like at least the left half of the letter "A".  time had ran out before I had time to find the culprit of this phenomenon.  Maybe tomorrow we will finally be done with lighting the letter "A".
