This tutorial was very helpful in getting me starting with my capstone project. This link is useful for those of you trying to create an Android app to control your processor. The reason I say processor is because it doesn’t necessarily work exclusively for the Arduino. Once you get the main concepts from the code, you can implement this by using another app creator other than the MIT App Inventor.
