OK! Got the Arduino and breadboard all wired and talking to my computer, now I just need to finish the Processing code, get the Arduino and Processing talking and finish the graphics. Why did I do this to myself?!
PS: the LEDs aren’t currently doing anything, I just wanted to make sure they work. I had an issue with them being super dull until I remembered the all important step of actually setting them up as an output. Also ran into an issue with the serial monitor not displaying values correctly. I realized it was due to the difference between using ‘ and “. Stupid little things like that have been very annoying to me tonight.
