This book explains 23 useful circuits that you can build.
Fun for beginners and a useful reference for experienced hobbyists.
The book will teach you about the most common of all Integrated Circuits - the 555 IC. The book is divided up into two parts - the practical experiments, and the technical reference about the 555.
All you need in order to build the projects is school science and a bit of common sense.
The theoretical part is a bit harder and it is assumes that you have some knowledge of electronics and that you know how a resistor, capacitor and a transistor works.

Please note that only the book is supplied. Professor Electronic Tutor Kits, 65 pages, 215 x 298mm.
