LED PROJECTS Archive

As I mentioned in my “Handmade 50W LED Flashlight” post, I built myself a high-powered flashlight. I can say it’s the best I could do with the materials I had..

The circuit is primarily designed to monitor, control, and protect the temperature of a power supply’s cooler. It can also be used in amplifiers and other cooler-equipped circuits. It can..

LED Spectrum Analyzer The low-pass filter is usually placed on the left and the high-pass filter is placed on the right on the display panel. You can experiment with filter..

Spectrum analyzer 8 channels (200Hz, 400Hz, 1kHz, 2kHz, 4kHz, 6kHz, 8kHz, 12kHz) 10 bargraph LED display is used. Audio Spectrum analyzer device is based on Atmel ATmega48 Microcontroller. It is..

A simple but useful and stable circuit. In this state, it easily operates a 50W lamp without needing cooling. Of course, it got a little hot in my 100W experiments..

This project is about the design and subsequent implementation of independently operating active cooling for LED components. Its basis is a 12V fan used for efficient heat removal. ATMega16 microcontroller..

I made a visually different version of the 10 channel 100 Led Spectrum Analyzer circuit that I used in the 2.1 sound system. The filter quality of the Led Spectrum..

The 10W LED Driver driver circuit is designed to operate a 10 watt LED matrix (3×3, 10-12V) with current limitation. It works in the Step-Down system. The ring core used..

Power LED driver Circuits made with TL494 pwm IC and MC34063 DC DC voltage converter ICs for LED Lighting. Actually there are a few more but I don’t mention them..

I will give information about how the HC-SR501 PIR motion sensor module works, HC-SR501 Features and its use with LDR. The HC-SR501 PIR sensor module can be used not only..
