When Make: Electronics was published about five years ago, it was widely hailed as the greatest book about learning electronics ever written. With beautiful photos, easy-to-read schematics, clear, jargon-free text, and dozens and dozens of fun and educational projects, author/illustrator Charles Platt made a book that has ended up in every makerspace and library I've visited.
A few weeks ago the Second Edition of Make: Electronics came out, and it's even better than the first edition. Charles rewrote the text, replaced the photos of breadboarded circuits with diagrams showing component placement, included new projects, added new photographs with a ruled background to indicate the scale of tools and components, and included a chapter on Arduino.
This is the book to get if you want to learn electronics.
