Thanks! I'm definitely an Arduino padawan, so it was important for me to write down what I learned, messed up, and still want to figure out. It just feels good to be combining code with physical hardware, even if its just a tiny little LED. I'm also reading CODE by Charles Petzold at the same time and each chapter is blowing my mind (while requiring several re-reads). Oh, and I'm watching Halt and Catch Fire. So, I'm firing on a lot of hardware cylinders right now.
