Hello and thanks for replying!
So to be more specific... I am working on the engineering kit. I was on the drawing robot and got as far as chapter 4.2 when I decided to take a break. I came back to my robot and code when suddenly nothing was working. However, I did leave Matlab open on my laptop as I took my break. I then backtracked the steps and tried to restart from the beginning of chapter 4 but nothing worked. The project consists of scripts/tasks in Matlab, so I shut it down, restarted it and tried again with no luck. I got out of Matlab and tried to do a simple sketch (ServoTest.ino) from the Arduino motor carrier library but get this error:
