Integrated Circuit 555 Projects (BP)

Every so often a device appears that is so useful that one wonders how life went on before without it. The 555 timer is such a device. It was first manufactured by Signetics, but is now manufactured by almost every semiconductor manufacture in the world and is inexpensive and very easily obtainable. Included in this book are basic and general circuits, motor car and model railway circuits, alarms and noise makers as well as a section on 556, 558, and 559 timers. A reference book of invaluable use to all those who have any interest in electronics, be they professional engineers or designers, students or hobbyists.
