So I have been trying to get project 14 working on the Arduino. However, the logo just changes colors wildly, and takes no input from the Arduino - when I take out the white knob, it does nothing for the program. The code is correct- I typed it twice; I used the processing code both from the website with Processing 3.2.3 and from my more outdated Aruduino book with Processing 1.5.1. Each time, it did the same thing - values appeared in the console on Processing, but the values were random, and not connected to the Arduino. The color change on the logo matched those values.
If it makes a difference, I loaded the image from my desktop (I did save it in sketches in Processing) and not the web, since the computer I was using was not connected to the internet. Also, I did used this tutorial: https://forum.arduino.cc/index.php?topic=415066.0 to get rid of an error on Processing 3.2.3. Still, it did not work!
Can someone please help me?!
