If you’re not familiar with the 555 timer, suffice it to say that ... Perhaps the most common use is as an astable multivibrator or RC relaxation oscillator. In this role, an external resistor ...

There is nary a microcontroller to be found on this circuit sculpture, which uses a pair of astable multivibrator(s) to light two sets of LEDs that represent air being inhaled and exhaled.

and switching circuits. In this chapter we discuss the three types of multivibrators, the 555 Timer, and the Schmitt trigger. Sinusoidal oscillators are discussed in Chapter 10. An astable or ...

The personal astable multivibrator is one popular product with a long pedigree, and it too has been enhanced by the addition of a CPU. The datasheets for these devices are notoriously incomplete. It's ...

As with many inventions, two people had the idea for an integrated circuit at almost the same time. Transistors had become commonplace in everything from radios to phones to computers, and now ...

When TV shows and movies need to use a phone number as part of the story, they typically use one that starts with 555. We spoke with an official historian at AT&T to find out why these three ...

For electricity to flow, everything needs to be connected in a big ring. It’s called a circuit. For example, the lights in most houses and flats are part of a circuit controlled by the consumer ...
