I m trying to print a phrase dEaF on LED screen, but I have no clue how to write it...
01234567
--------d
------dE
-----dEa
----dEaF
---dEaF
--dEaF
-dEaF
dEaF
EaF
aF
F
01234567 indicates the position on the LED
where '-' indicates space
first, I have to print 'd' on the screen, after one second, the screen should show 'dE' instead of 'd' and so on...
