We are about to switch to a new forum software. Until then we have removed the registration on this forum.
Is there a small program or library(maybe) that does simple addition? Or is this something I need to write a function for?
I need to be able to take input from 6 different buttons (who's choices are between 0-3), add them together and display the result.
It doesn't need to be able to do anything other than the addition. I have searched around but can't find anything similar to what I need, and I am not a very good programmer - still learning processing.
