In this post I will show how to construct an Arduino automatic street light dimmer circuit, which can reduce its brightness when no vehicle is passing in the road to save power. Overview We will be exploring the methodology of sensing the vehicle or human being without false detection which may occur due to animals […]

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 […]
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 […]
AC Light Dimmer Circuit
In this post I have explained through two examples how to build a simple110 V or 220 V AC light dimmer circuit for controlling light intensity with pot, using the principle of triac phase chopping. A 220V dimmer switch circuit is basically a triac/diac based AC mains voltage regulator circuit which can be used for […]
Solar Boost Charger Circuit with LED Driver Dimmer
In this article I have explained a simple solar boost charger with LED driver circuit which also includes a single push dimmable feature. The idea was requested by Mr. Ashutosh. Technical Specifications Hi swagatam,Myself Ashutosh. I m very new to ur website, n i ll say u r superb, u r doing one of the […]
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 […]
