In this post I have explained a simple circuit which can be used for producing a slow fading light effect each time it’s switched OFF. The application can be typically used in car interior lights. Designed by: Abu-Hafss The Circuit Concept Most of the modern cars are equipped with circuitry which switches on the Car’s […]

Automatic Street Light Dimmer Circuit
In this post I will show how to construct an Arduino automatic street light dimmer circuit, which can reduce its brightness when no vehicle is passing in the road to save power. Overview We will be exploring the methodology of sensing the vehicle or human being without false detection which may occur due to animals […]
Light Controlled Sound Effect Generator Circuit
This unique circuit allows you to create many different sound effect outputs simply by moving your hands over a couple of light dependent resistors, by varying the intensity of incident light over the LDRs. By Ramesh Powar The generator has two different cells LDRs that control a sound – burst oscillator circuit. One LDR controls the tone […]
SMPS 50 watt LED Street Light Driver Circuit
The post presents an SMPS based LED street lamp driver circuit which can be used for driving any LED lamp design right from 10 watts to 50 watts plus. Using the IC L6565 The proposed 50 watt (and higher) LED street light driver circuit uses the IC L6565 as the main control device, which is […]
PIR Controlled Solar Garden Light Circuit
In this post I have explained a simple automatic PIR controlled solar garden light circuit which will switch ON the LEDs only under two conditions: when it is completely dark and when a human being is detected in the vicinity. The above feature of the circuit ensures that the LEDs are turned ON only when […]
2 Simple Light to Frequency Converter Circuits for Transforming Light into Pulses
In this article we are going to see what is a light to frequency converter circuit, how it works, how to use it in a project, and its specifications. No matter which category you belong to, professional, hobbyist, engineer or student, modular components always reduce half of our headache while designing circuits. They eliminate the […]
