We are about to switch to a new forum software. Until then we have removed the registration on this forum.
I am just starting with arduino.
I just try to port a program from p5 to arduino and get lots of errors .
1st I use final int to declare const and use them in switch
aduino seems not to know final, but when I delete final, my switch doesn't work. So how can I declare a const? (I mean I could use 0 and 1 and 2 in the switch but urghs...)
2nd: I use lot of 2D arrays, but the  puzzles the Arduino compiler... how can I do a 2D array here?
Thanks a lot!
