Sequential LED Array Light Circuit
In this article I have explained how to make a sequential LED array light circuit with an sequentially illuminating LED forming a bar graph kind of LED formation. Introduction In this article I have explained a simple method of making an incremental LED light using the IC 4017, which is rather equipped with specifications not […]
Light Meter Circuit with LED Bar Graph
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 […]

LED Light Circuit for Street Vendors, Hawkers, Shopkeepers
In this article I have explained how to build a very simple, low cost LED lamp with charger. This unit can be used by any street seller, vendor, hawker, to illuminate his shop during night. Thus, the light will ensure that the seller can continue to do business even after dusk to enhance his profits. […]
Light Emitting Diodes (LED) Explained
The full form of LED is Light Emitting Diode. LEDs are special type of semiconductor diodes which emit light in response to a potential difference applied across their terminals, hence the name light emitting diode. Just like a normal diode LEDs also have two terminals with polarity, namely anode and cathode. To illuminate an LED […]
