555 One-Shot Timer Project
I suppose that if you set out to build a Blaster Pistol, you should expect that somewhere along the way you might be required to construct a Uranium PU-36 Space Modulator, but I wasn’t prepared to build a Oneshot Monostable Multivibrator.
When I first thought about adding...

This small Timer circuit by sam(good electronic man).
sam say “A small circuit that can find a lot applications of measurement time. She has the possibility us inform with sound signal from the BZ1. At the same time, exist the possibility drive a external circuit via the optocoupler IC2, after we connect...

555 Timer as an Astable Multivibrator jojo September - 9 - 2009 Share
An astable multivibrator, often called a free-running multivibrator, is a rectangular-wave generating circuit. Unlike the monostable multivibrator, this circuit does not require any external trigger to change the state of...

555 Timer as Monostable Multivibrator jojo September - 9 - 2009 Share
A monostable multivibrator (MMV) often called a one-shot multivibrator, is a pulse generator circuit in which the duration of the pulse is determined by the R-C network,connected externally to the 555 timer. In such a vibrator,...
