The Jee Book: Adventures in Physical Computing by Jean-Claude Wippler
English | PDF | 2015 | 385 Pages | ISBN : N/A | 19.17 MB
A book about having fun with electrons, bits, and atoms in and around the house.
This is a hands-on book about technology,and more specifically Physical Computing-the intriguing combination of computer hardware and software with connections to the real world via sensors, actuators, and direct user interfaces.
