The 555 timer IC has been around now for quite some time and the list of potential uses for this device appears to be endless. This article contains a few examples of circuits that you might ...

[FightCube] wrote in recommending a very helpful piece of circuit simulation software for those of you still constructing entries for the 555 design contest. LTSpiceIV, available from Linear ...

This circuit enables the on/off times of a 555 timer to be independently varied over a wide range. This is not possible with a conventional 555 circuit with the RC network being charged from the ...

The Senior Pillbox aims to provide a low-cost, fully electronic circuit-based solution with minimal human intervention ...

Save guides, add subjects and pick up where you left off with your BBC account. The 555 timer is a versatile integrated circuit (IC) that can control timing in electronic circuits. It's one of the ...

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 ...
