What are the best books and free online resources to learn about robotics, electronics, etc? I am interested in getting into robotics, but I do not know where, or how to start. I am entering high school, and I have little knowledge about how this stuff works, so I would like to learn from the beginning. I don’t mind buying books, or getting them from the library, but I don’t want to but any courses or anything. However, any free resources that you can recommend would be appreciated. Also, sorry for this being so long and repetitive, but this subreddit doesn’t let me post unless I use a lot of characters.
