White LEDs have become so common nowadays that even school kids today know how to use them for making simple LED projects. LEDs are typically used for illuminating purposes, the discussed circuit is also intended for similar applications. The post talks about how to wire LEDs and battery to make a simple DIY LED flashlight. […]
Newly Updated Circuit Projects:
Light Dependent LED Intensity Controller Circuit
In this post I have explained a simple ambient light dependent LED illumination controller circuit. The light fades or intensifies proportionately i response to the ambient light conditions. With brighter daylights, the LEd illumination gets softer and vice versa. The idea was requested by one of the dedicated members of this blog. Technical Specifications While […]
Diwali, Christmas 220V Lamp Chaser Circuit
In this post I have explained a simple, compact, 220V, 120V transformerless light chaser circuit which can be used for illuminating 220 V mains operated lamps or bulbs in a sequential chasing manner. Main Technical Features The chasing or running lamp effect can be altered by means of pot controls. The system can be used […]
10 Simple LED Chaser Circuit Diagrams Explained [Knight Rider, Scanner, Reverse-Forward, Cascaded]
In this article I have explained the construction of 10 interesting yet simple LED chaser circuits, which not only create beautiful running light effect but are also easy to build. We also discuss how to modify these into a design popularly known as “knight rider” chaser circuit. These primarily incorporate LEDs as well as mains […]
Blinking 3 LEDs (R,G,B) Sequentially Using Arduino Circuit
In this post I have explained how to run or blink three LEDs in sequence using Arduino. The post was written and submitted by: Jack Franko PROGRAM/* make RGB LEDs to blink in series one by one at intervalof 1000MS */ int R = 12;int G = 11;int B = 10;void setup(){ pinMode(R,OUTPUT); pinMode(G,OUTPUT); pinMode(B,OUTPUT);}void […]
How to Build a Grow Light Circuit
In this post I have explained a typical grow light circuit application for plants in order to stimulate photosynthesis effect in an artificially lit environment using multicolored LEDs. The idea was suggested by Mr. Jack. The Circuit Objective I would like to donate to your site and pay you also for work you do on projects […]
