With no external components, a 555 can be turned into an oscillator that runs typically in the range of 1 to 2.5mHZ –or who needs a timing capacitor? It is essentially a stripped down version of the ...

Since its invention over a half-century ago by Hanz Camenzind at Signetics, the familiar 555 analog timer (in league with its updated pin-compatible CMOS descendants) has become an iconic design ...

The 555 timer is one of that special club of integrated circuits that has achieved silicon immortality. Despite its advanced age and having had its functionality replicated and superceded in almost ...

From simple buzzers to an Atari Punk Console, the simple 555 timer chip is the foundation of a whole lot of interesting lo-fi synth projects perfect for beginners. [Steven] put together a great ...

With this simple circuit connected to a serial port, small capacitance deviations on the order of 0.01 pF can be easily sensed over a wide range of several hundred picofarads (see the figure).... With ...

The 555 timer IC is an integrated circuit (chip) which is used in a variety of timer, delay, pulse generation, and oscillator applications. 555 Signals and Pinout (8 pin DIP) Figure below shows the ...
