I'm also new to Arduino and C++, but have done programming in the (distant) past. From what I know i usually you have to declare the array name and size alongside the included libraries and global variables. This first loop is in control of the rows of the matrix. Some of the patterns, however, can be run in reverse (say light up left to right, and then right to left). Sep 14, 2016 · I think I got the idea but I´m not sure, this is the practice: Define and initialize two arrays of 3 x 3.
