Major progress! I redid a lot of my wiring, and I've got lights and sounds going. Super cool!
The problem I'm having now it that when I add in the barcode version of the sketch, it goes kaput. I tested power, and there is about 4.3V going into the SX1509, but no cool little running lights. And of course, that also keeps everything else from doing anything. If I upload the other sketch, without the bargraph, it works again.
I'm using a Mega2560 board, and I'm plugging the SCL plug into the SCL pin on the Arduino, and the SDA from the SX1509 into the SDA on the Arduino. I haven't made any changes to the code.
Where do you suggest I begin my trouble shooting? Do you have any other ideas? This is the last piece of the wiring puzzle for me, so if I can get past this hurdle, I'm all set!
