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 […]
LED Meteor Shower, Rain Tube Circuit
In this post I have explained how to design an intriguing LED light effect that generates a collapsing metor shower like appearance. The idea was requetsed by Mr.Pinto Mondal. Technical Specifications I am very grateful of your work. Sir I want to make a circuit,which available in the market like 1 or 1.5ft long led […]
200, 600 LED String Circuit on Mains 220V
In this post I have explained the construction of a 200 to 600 LED circuit project, using series parallel LEDs for creating an alphabetical display sign board. The idea was requested by Mr. Mubarak Idris. Circuit Objectives and Requirements I need a blinking LED light that show”WELCOME TO” blink and then “COLLEGE OF ENGINEERING” base […]
Controlling LED Strip Light ON/OFF and Brightness with any Remote Control
In this post I will show how to construct LED strip controller circuit using Arduino, which can turn ON/OFF and decrease/increase brightness of LEDs using ordinary IR (Infrared) remote. What is LED Strip Light? (For noobs) If you are not familiar with LED strip lights, let’s understand what it is. LED strips (sometimes called as […]
“WELCOME” LED Display Circuit
In this post I have explained how to make a chasing “WELCOME” display circuit sign board, which illuminates each alphabet sequentially until all the 7 alphabets are lit and then the whole display shuts off, the cycle continues permanently as long as the circuit is powered. Overview I have already discussed a similar concept explaining […]
