A low pulse on this pin (below 1/3 of VCC) sets the internal flip-flop and makes the output go HIGH. When the voltage on this pin reaches 2/3 of VCC, it resets the flip-flop, and the output goes LOW.

Today we are going to create a strobe light for the tips of the wings of an rc airplane using a 555 timer (NE 555 or lm 555 IC) this circuit is very easy to make with few components and most ...

Abstract: The main purpose of this paper is to explore the oscillating characteristics of an astable multivibrator based on memristor and 555 timer. An analog circuit is utilized to simulate magnetic ...

DEAR MISS MANNERS: I have had a recurring situation happen for the past five years -- since I have been married. My husband and I enjoy taking photos of us together using a timer on the camera. We ...

Use this issue to get your lab and experiment repositories hosted on Virtual Labs. This issue also is used to host labs and their experiments that have been migrated to Phase 3 lab/exp format from ...

Many of us could sit down at the bench and whip up a 555 circuit from memory. It’s really not that hard, which is a bit strange considering how flexible the ubiquitous chip is, and how many ways it ...

Normally I cover a new product or technology in my Lab Bench section. However, since this is the last one to appear in a physical print issue, I thought I would look back at a technology that had a ...
