In this post I have explained a simple IC 555 based PWM controller circuit which may be used for controlling the intensity of a specified LED bank or an 12V LED strip light. The idea was requested by Mr. Rajdeep. Technical Specifications Fantastic blog you have got. I learnt many things from your blog. I […]

How to Add a Dimmer Facility to a LED Bulb
In this article I have explained how to make an LED dimmer circuit for enabling a dimming facility to any mains operated LEDs bulb. Update: [Using Capacitors, it Works] If you think PWM dimming control might not work for commercial LED bulbs, then the best method is to use series capacitors, which might just do […]
Push-Button Light Dimmer Circuit
In this post I have explained the construction details of a triac based push-button dimmer circuit which can be used for controlling incandescent, and fluorescent lamp brightness through push-button pressing. Another feature of this dimmer is its memory, which retains the brightness level even during power outages, and provides the same lamp intensity after power […]
LED Night Lamp with Dimmer Circuit
In this post I have explained a simple plug-in type night lamp circuit with delayed switch OFF and dimming facilities. The entire circuit is built using a transformerless power supply which ensures that the unit is very compact and can be plugged into any existing 220V mains AC socket. Circuit Description The electronic schematic of […]
Automatic Vehicle Headlight Dipper/Dimmer Circuit
The circuit described here can be built and used in your vehicle for an automatic dipping and dimming operation of the vehicle headlamps, in response to the intense lights coming from an opposite vehicle headlamps. What’s a Dimmer/Dipper in Automobiles An automobile headlight dimmer/dipper is a circuit which automatically switches the headlight intensities of vehicles arriving from […]
Using a Fan Dimmer for Controlling LED Intensity
The circuit idea I have I have explained in this article can be used for controlling the intensity of many LEDs through a ceiling fan dimmer switch unit. This circuit was requested by Mr. Joseph who wanted a simple method through which an ordinary home dimmer switch could be integrated with a chain of LEDs for controlling its brightness from […]
