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 […]

Adjustable Timer Circuit Using IC 555
IC 555 adjustable timer explained here can be adjusted from any time delay 1 second to 3 hours for operating any load through a relay control The produced time delay is fully adjustable and the user has the freedom to set the time period as desired. There are many ways of making simple timer circuits […]
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. […]
How to Generate PWM Using IC 555 (2 Methods Explored)
The IC 555 is an extremely useful and versatile device which can be applied for configuring many useful circuits in the field of electronics. One very useful feature of this IC is its ability to generate PWM pulses which can be dimensioned or processed as per the needs of the application or the circuit. What’s […]
Input Trigger Synchronized Monostable Timer Using IC 555
Here we study a simple IC 555 based monostable circuit whose output monostable time duration starts only after the input trigger is released thus making sure that the trigger ON time duration is added with the monostable’s pre-programmed ON time duration. The idea was requested by Mr. John Brogan Technical Specifications I would like to […]
