Ok, I may be jumping the gun here a little bit. Feel free to call me impatient. But, I have now bought a littleBits set with the Arduino coding bit for my six year old so we can start learning to code and learn about electronics. https://www.makerspaces.com/getting-started-with-arduino-using-littlebits/ The coding part is obviously going to be a little bit over his head for a little while, but I thought I would start teaching him about it. I have done a little bit of research to educate myself about Arduino coding, and I found Ardublock, which seems like a neat add on that may be good to help simplify the coding for him and help smooth out the learning curve until he's ready to start working in with Arduino himself. I have done some programing in Basic and Pascal back in my younger days, but I know nothing about Arduino. Is there a source for beginning Arduino coding that I can use to get started teaching myself the basics?
