Watch the video given below to get a better idea on how LED works? Â A light emitting diode (LED) is known to be one of the best optoelectronic devices out of the lot. The device is capable of emitting a fairly narrow bandwidth of visible or invisible light when its internal diode junction attains a […]
Introduction. Here is low cost circuit that can be used for implementing a warning light on the top of tall structures as a warning for low flying aircrafts. Usually such lights are just stay glow type. Here our light is a flashing type, and surely this will draw more attention and of course add more
Description. This is a modification of the circuit Simple Lamp Dimmer/Fan Regulator previously posted here. The working of the circuit is same as that of the previous, but in addition a snubber circuit consisting of resistor R4 and capacitor C3 is included to improve the performance of the triac T1. A fuse is also included
A Simple Light activated switch Description. This is the circuit diagram of a light activated switch based on National Semiconductors comparator IC LM 311 and a LDR. The circuit is based on a voltage comparator circuit wired around IC 1.The non inverting in put of IC1 is given with a reference voltage of 6V using
In this project guide, we’re doing a simple Musical Light Chaser circuit using two digital IC’s and some associated components. This is basically a hobby circuit, which you can build for Halloweens or Christmas decorations. Description Here is a simple state of the art musical chaser circuit that can be used in discotheques or even
In this project, we’re building a simple Lamp Flasher circuit using NE 555. A lamp flasher is nothing but a lamp dimmer circuit – where the lamp is turned ON/OFF at set frequency or time intervals. We’ve designed this circuit using the most popular and common components like the NE/SE 555 IC. Let’s begin our
This is an interesting project where the intensity of a lamp can be controlled by touch. Most lamps only have an on/off switch. They don’t have any regulators to increase or decrease the intensity of lighting. Having such a built-in feature is available for some expensive lamps. But the same can be achieved without emptying
