In this article I have explained 3 different light meter circuits for measuring power of light. In the first method we will use only a solar cell and a multimeter, in the second method we will use an op amp and a moving coil meter, and in the third method we will see how a […]

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. […]
Arduino Random RGB Light Generator Circuit
The article discusses a simple,Arduino red, green, blue LED light effect generator circuit in a random pattern. In one of the earlier posts we came across a similar RGB LED effect generator circuit using Arduino which was programmed to produce the effect in a flowing sequential manner, whereas here the set up can be expected […]
Arduino RGB Flowing Sequential Light Circuit
In this post we are going to make a simple but useful circuit that can make an RGB LED glow in a nice flowing way. That is not just random blinking, but smooth sequential lighting of red, green, and blue one by one. This is done using Arduino, so you need to have some basic […]
LED Strip Light Dimmer Controller Circuit
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 […]
220V/120V LED String Light Circuit using a Single Capacitor
In this post I have explained how to make a LED string light which can be operated from 220V mains through a single inexpensive PPC capacitor. The idea was requested by Mr. Basit Momin.WE STRICTLY CAUTION YOU THAT YOU BUILD THIS CIRCUIT ONLY IF YOU ARE AWARE OF THE DANGERS OF MAINS AC AND KNOW […]
