The 555 is a single-chip version of a commonly used circuit called a multivibrator, which is useful in a wide variety of electronic circuits. The 555 timer chipis probably the most popular integrated circuit ever made.
The IC 555 can be also wired as an accurate comparator and finds important applications in this mode of operation. One classic example is a light threshold detector circuit which may be suitably used for automatically switching street or porch lights when dusk falls and switch them OFF at daybreak. 47 Projects to Do With a 555!: These are a whole bunch of things to make with the 555 timer IC with a note for each picture. I do not take credit for these schematics, they were made by Collin Mitchel. As you would probably think it took me a very long time to make this but it. 555 timer was first introduced by signetics corporation in 1971 as SE555/NE555. It is a affordable, stable and user friendly IC in application such as monostable and bi stable. Here is the list of 40 555 timer circuits that can help you in understanding 555 timer functions.First five circuits explains about 555 timer and its different modes. Astable multivibrator is also called as Free Running Multivibrator. It has no stable states and continuously switches between the two states without application of any external trigger. The IC 555 can be made to work as an astable multivibrator with the addition of three external components: two resistors (R1 and R2) and a capacitor (C). 555 timer is an important device in embedded system design which is frequently used in several electrical and electronics projects for generating clock pulses. The 555 timer circuit is produces precise clock pulses which can be used to control the applications as over requirement.
You can use the 555 chips for basic timing functions, such as turning a light on for a certain length of time, or you can use it to create a warning light that flashes on and off. You can use it to produce musical notes of a particular frequency, or you can use it to control positioning of a servo device.
Here is the arrangement of the eight pins in a standard 555 IC. The 555 comes in an 8-pin DIP package.
Here are the functions of each of the eight pins:
When used in a schematic diagram, the pins of a 555 timer chip are almost always shown in the arrangement depicted here. Supply voltage is at the top, ground is at the bottom, inputs are at the left, and outputs are at the right.
