Here is information to look over including advanced topics. There is a lot of information on the web that is very useful, but there is also a lot of complicated physics that you do not have to understand to get your projects working.

Want your own starter Arduino Kits?

If your feel TinkerCad Circuits is not enough for you, you can get your own starter Arduino Kits and other hardware on the following websites: Adafruit, Sparkfun, and Tinkersphere.
