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 […]

Christmas LED Candle Light Timer Circuit
In this post I have explained a sequentially advancing 25 LED timer circuit which may be initiated on the 1st day of December so that each LED lights up on each day until the 25th of December (on Christmas) when all the 25 LED can be seen lit up. The circuit was requested by Mr. […]
Musical Christmas Decoration Light Circuit
A very interesting musical Christmas decoration light circuit can be built using a single IC, and some other few passive components, let’s learn the details as furnished below. By: Ritu Panday How it Works The circuit of a selectable muti-musical song player with 5 sequential light pattern generator is discussed here using just a single […]
Xenon Strobe Light Control Circuit
The circuits presented in the following article could be used for generating strobed lighting effect over 4 Xenon tubes in a sequential manner. The proposed sequential xenon lighting effect could be applied in discotheques, in DJ parties, in cars or vehicles, as warning indicators, or as decorating ornamental lights during festivals. A wide range of […]
RGB Spot Light Generator Mixer Circuit
In this RGB spotlight mixer circuit project, 3 individual spot lights are used, having red, green and blue focus light bulbs in them. The lights can be focused on walls, ceilings or floors to create interesting slow rising, slow fading red, green blue light patterns that mix and diffuse to generate interesting, additional secondary colors. […]
RGB Light Strip Controller Circuits
In this post we are going to see how we can construct an RGB LED light strip controller circuit for PC cabinets and also for general decoration purposes. In this post we will construct a couple of RGB light strip controller designs, one for a PC cabinets and one for general purpose which can be […]
