DC Lamp Dimmer Circuit using IC 555
In this post I have explained how to use the control pin#5 of the IC 555 to build a simple PWM controlled DC light dimmer circuit. The proposed DC lamp dimmer can be used for controlling the light intensity of any DC lamp having an operating voltage anywhere between 6 V and 12 V. The […]
IC 555 Astable Multivibrator Circuits
The IC 555 astable multivibrator is a configuration where the IC 555 output continuously switches between an ON state and an OFF state at a given frequency, determined by its RC timing components. Since in this configuration, the output of the IC 555 is never in a stable state, it is called an astable multivibrator. […]
Visitor Counter Circuit Using IC 555 and IC 4026
A visitor counter is a machine that counts the of number people who visited a place. Visitor counters are usually installed at the entrance and exit points of commercial buildings such as shopping malls, theme parks, museums, Airports, schools, departmental shops and other business etc. The registered counts on the machine are used for business […]
7 Interesting IC 555 Siren and Alarm Circuits
In this post I have explained how to use IC 555 to create 7 interesting siren and alarm sound effect generator circuits. The versatile astable multivbrator configuration of IC 555 allows us to implement it for making various types of sirens and alarm circuits. This becomes possible because an astable is basically a waveform generator, […]
10 Simple IC 555 Monostable Circuits Explored
In this post I have explained how IC 555 can be used for making 10 different types of monostable multivibrator circuits, such as one-shot type, debounce preventor, retriggerable type, touch switch monostable circuit and many more. A monotsable multivibrator circuit is a configuration in which, a short momentary pulse at the input of the circuit […]
