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 ...

By focusing on the simplest 555 circuits, [Diode] can show just what each pin on the chip does, using an outsized schematic that reflects exactly what’s going on with the breadboarded circuit.

LTSpiceIV, available from Linear Technology, allows you to construct moderately complex 555 driven circuits including common components such as capacitors, resistors, diodes, FETs, and more.

Figure 1 An astable 555 timer circuit based on an inductor ... His current interests include nonlinear phenomena and chaos in circuits, creative approaches to teaching and research, and adaptive ...

The 555 timer is a versatile integrated circuit (IC) that can control timing in electronic circuits. It's one of the most widely used ICs due to its reliability and flexibility.

which I show in my book “Essential 555 IC: Design, Configure, and Create Clever Circuits.” In the book, I walk the reader through the simplest use of a 555 timer to rather advanced techniques ...
