8 Channel Lighting Sequence Generator Circuit for Christmas, Diwali Decoration
In this post I will explain how to make one full adjustable lighting sequence generator which can control and illuminate many external bulbs through triacs in many different running patterns. We can make it so that user can change and select any sequence pattern easily. We will use Arduino for the full control part. Let […]
Single Ended nOOds, 300mm long Flexible LED Filament, Warm White 3V
So here we are talking about this cool looking thing called Single Ended nOOds, basically it is a type of flexible LED filament which is 300mm long which means around 30 cm, like one standard scale. It glows in warm white color and works nicely with just 3V DC. What is it, actually? This LED […]
Flashlight Circuit with Long Backup and High Efficiency
There are two main advantages of this highly efficient flashlight circuit with long backup. Firstly, it uses only a single 1.5V AAA cell and illuminates a 3.3V LED. Secondly, the 1.5V cell is consumed by the LED until there’s virtually no charge left in it. Due to these features, this flashlight is able to last […]
Smart Street Lamp Circuit with Motion Sensor
This simple yet highly sophisticated, smart LED street light circuit automatically switches ON a street lamp from low brightness to high brightness whenever it detects a moving object underneath it. This action is initiated only during nighttime, while during daytime the street lamp remains completely shut off. What this Circuit will do This advanced automatic […]
Automatic Night Activated Wireless Light Circuit for Paintings
In this article I have explained a basic wireless LED light circuit that may be used to autonomously turn on LED lights to illuminate artworks at nighttime.
