Excellent article, Ian. As you mentioned, most articles on this subject are overwhelming to the beginner - so they just say 'I will worry about that later' and never get back to it. You struck a really nice balance between readability and utility. Thank you.
Hello Luis -
Great to see you have caught 'Arduino Fever' :-)
Just started a new company to help accelerate the adoption of Maker/Arduino/IoT into K-12 schools. It would be great to catch up and discuss possibilities.
