I am curious why you haven't tied your sda and slc pins to vcc with 4.7k resistors like the data sheet suggests?
It would be a matter of having enough ram for processing the array of LEDs values...
Great job, not so good about the pine, but nice to see that it fell clear of the house or other structures -- At least I hope it did. Also nice that you took the extra step/cost of not using treated timbers. A++ job.
Nice to hear, the storm that followed a prolonged dry spell has placed stressed on the local gum (eucalyptus) trees. 6 major sized limbs completely totalled my little boys playhouse... :(
