Over 45 Builds for the Legendary 555 Chip (and the 556, 558)

The 555 timer IC, originally introduced by the Signetics Corporation around 1971, is sure to rank high among the most popular analog integrated circuits ever produced. Originally called the IC Time Machine, this chip has been used in many timer-related projects by countless people over decades.

This book is all about designing projects based on the 555 timer IC. Over 45 fully tested and documented projects are presented. All projects have been fully tested by the author by constructing them individually on a breadboard. You are not expected to have any programming experiences for constructing or using the projects given in the book. However, it’s definitely useful to have some knowledge of basic electronics and the use of a breadboard for constructing and testing electronic circuits.

Some of the projects in the book are:

  • Alternately Flashing Two LEDs
  • Changing LED Flashing Rate
  • Touch Sensor On/Off Switch
  • Switch On/Off Delay
  • Light-Dependent Sound
  • Dark/Light Switch
  • Tone Burst Generator
  • Long Duration Timer
  • Chasing LEDs
  • LED Roulette Game
  • Traffic Lights
  • Continuity Tester
  • Electronic Lock
  • Switch Contact Debouncing
  • Toy Electronic Organ
  • Multiple Sensor Alarm System
  • Metronome
  • Voltage Multipliers
  • Electronic Dice
  • 7-Segment Display Counter
  • Motor Control
  • 7-Segment Display Dice
  • Electronic Siren
  • Various Other Projects

The projects given in the book can be modified or expanded by you for your very own applications. Electronic engineering students, people engaged in designing small electronic circuits, and electronic hobbyists should find the projects in the book instructive, fun, interesting, and useful.

Long lasting play toy!
Color: Multicolor
Tuffy toys in general are great and they are a pretty good deal on Amazon. They are not indestructible, and if your dogs use them as chew toys they will eventually break through. My dogs have had this Armadillo since Christmas (and they do chew on it some) and the only thing missing is an ear. They like to play tug-of-war with it a lot. This is a bigger toy, but even my forty pound dog plays with it. I would not recommend this toy for dogs smaller than Border Collie size. You can make these Tuffy toys last longer if you don't allow your dogs to chew them--when your dogs starts chewing on non-chew toys trade them for a chew toy and when you catch your dog chewing on a chew-approved toy reward them for chewing. Eventually your dog will catch on and realize that if they want to chew there are certain toys that are allowed for that. In addition to being a great play toy this is a pretty cute toy too!

Not Tuff
Color: Black Yellow Phrog, Color: Black Yellow Phrog
Absolutely terrible and not “tuff” at all. My chocolate lab had this thing destroyed in less than two hours. I would not recommend these for the price.

Cute but Not Durable
Color: 2PK Green Leaping Phrog
⭐️⭐️⭐️⭐️ Cute but Not Durable Super cute toy—my dogs loved it right away! Unfortunately, they chewed the head off within a few hours. I ordered a second one because they were so into it, but the same thing happened again. I won’t be ordering a third, but they still play with their two headless frogs. So while it’s not the most durable, it definitely kept them entertained!

Great toy
Color: Black/Orange
This brand really makes durable toys. They outlast every other toy my dogs have. One dog loves to get the squeaker out of any toy, but he doesn’t rip this one apart. Obviously it won’t last forever, but no toy does! Some other brands of toys only make it a day or two, while these last months to years.
