Where/How to learn about Engineering basics? Answered
I have been recently looking into engineering and how to build different equipment, and am wondering where people learn to do these kinds of things. The first thing I saw that had inspired me was a man who built a glove and software that replicated finger/hand movements in motion capture fashion that was useful to me because I do 3D animations which is helped by motion capture. I had built it because he had left a step-by-step tutorial on how to do so, and it worked perfectly. The thing that upset me was that I have no understanding of how these parts work, I just bought the equipment and put it together based on his instructions. So I am wanting to ask how I learn about this stuff? Things that I am wanting to learn I believe are geared around Micro controllers (EX: Arduino), MotionTracking Device's (EX: MPU-9150), Multiplexers, and other stuff that revolves around that. I have been looking for tutorials and books to help but have had no luck. Also one of the most frustrating things I faced when putting the gloves together was that I had no idea what 'SIG', 'VCC', 'GND', or any of those meant. I understand that I might sound pretty stupid, but I am genuinely interested in this am looking to learn about it, I just do not know how to. Thank you for any reply in advance.
