I just ordered an Arduino and wanted to know if it could do the following using a 4x4 matrix:
Read a text file that has this in it:
1X1X // LED Row A
X2X2 // LED Row B
X3X3 // LED Row C
4X4X // LED Row D
It would be read left to right, reading all four lines at once. So for instance:
First read would show LED 1 of Row A ON and LED 4 or Row D ON at same time.
Second read would show LED 2 of Row B ON and LED 3 of Row C ON.
Third read, same as First,
Fourth read, same as Second.
There would also be a delay between each read and LED's would turn off in between.
Anyone have any ideas on how to accomplish this? My biggest concern is how to read all four lines at once left to right?
Would I need to store the values of Row A first, then Row B, then C, then D and recall them all simultaneously?
Thanks
