A simple RGB (Red, Green, Blue) moving or scrolling LED display can be made using a few 4017 ICs. I have explained the procedure in detail. Understanding RGB LED RGB LEDs have become quite popular these days due to its three-in-one color feature, and because these can be driven independently using three distinct supply sources. […]
Newly Updated Circuit Projects:
Make this 2 Pin Bi-Color LED Flasher Circuit
This transformerless mains power supply circuit will allow flashing of a Bi-color 100 LED string, in an alternately switching red, green effect. Using 2-pin Bi-color LEDs The proposed circuit can be used as a Bi-color LED flasher, for generating an alternate red, green flashing effect over a string of 100 LEDs. Bi-color LEDs are available […]
Simple RGB LED Color Mixer Circuit using LM317 IC
In this post I have explained a simple LM317 IC based RGB 3 watt LED color mixer circuit, which can be used for demonstrating the color mixing effects of red, blue, green colors as specified in the standard color charts. The idea was requested by Mr.Praveen. Technical Specifications My name is Pravin, I work in […]
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 […]
LED Obstruction Light Circuit
Obstruction lights are warning lights that we see at the top of tall structures like towers and skyscrapers, installed for indicating the aircrafts and other flying objects about these obstructions. These lights alert the flying aircrafts regarding the minimum height they should maintain above these tall structures to avoid a possible collision and accidents. Obstruction […]
Remote Controlled Solar Lamp Intensity Controller Circuit
In this post I have explained a simple remote controlled solar lamp intensity controller circuit which can be used for controlling the street lamp LED intensity without practically reaching for the LED box. The idea was requested by one of the dedicated members of this website Circuit Objectives and Requirements I have successful build this […]
