The blurb:

Want to learn even more about electronics in a fun, hands-on way? If you finished the projects in Make: Electronics, or if you’re already familiar with the material in that book, you’re ready for Make: More Electronics. Right away, you’ll start working on real projects, and you’ll explore all the key components and essential principles through the book’s collection of experiments. You’ll build the circuits first, then learn the theory behind them!

This book picks up where Make: Electronics left off: you’ll work with components like comparators, light sensors, higher-level logic chips, multiplexers, shift registers, encoders, decoders, and magnetic sensors. You’ll also learn about topics like audio amplification, randomicity, as well as positive and negative feedback. With step-by-step instructions, and hundreds of color photographs and illustrations, this book will help you use – and understand – intermediate to advanced electronics concepts and techniques.

About LEAP

LEAP is my personal collection of electronics projects - usually involving an Arduino or other microprocessor in one way or another. Some are full-blown projects, while many are trivial breadboard experiments, intended to learn and explore something interesting.

Projects are often inspired by things found wild on the net, or ideas from the many great electronics podcasts and YouTube channels. Feel free to borrow liberally, and if you spot any issues do let me know or send a pull-request.

NOTE: For a while I included various scale modelling projects here too, but I've now split them off into a new repository: check out LittleModelArt if you are looking for these projects.
