Jon Roman and Donald Schelle have a design idea on how to simulate a high power led to test your driver circuit. Testing the driver circuit using LEDs, although easy, yields only typical results because the tests don’t factor in worst-case LED parameters and often generate...

Ted Yapo has designed a multi-year always-on LED replacements for gaseous tritium light sources. TritiLEDs are always-on battery powered LED glow lights for general night-time marking use. Radioactive gaseous tritium light sources (GTLSs) are allowed in the United States in several...

by Julien Happich@ edn-europe.com Designed for infrared illumination for cameras, surveillance systems or machine vision, the Oslon Black SFH 4715A infrared emitting diode (IRED) boasts a low thermal resistance of maximum 11K/W, delivering a 850nm beam with an optical output of 770mW...

sagnikb7 @ instructables.com show us how to build a wireless mood lamp using Arduino and BLYNK app. In this tutorial we will be creating a MOOD (you can create any color you can imagine to fit your mood) light, that can be controlled from your smartphone, we will be creating the APP...

Vitaliy_M @ instructables.com has build a nice little LED flashlight. The flashlight turns on automatic for 60 seconds when it senses that the room is dark enough. To turn on manual light for additional 60 seconds you need to push the RST button. Smart LED Flashlight -...

Today I want to make a LED Scroll Bar as is shown in the picture above. Ten LED strips can flash in different effect by using a control board. Components: LED strip, Arduino Nano, Dupont line and a control board. Arduino LED Scroll Bar using easyEDA -...

circuitstoday.com guide us to the basics of LED and bargraph usage in Proteus software. In this post we will be learning on how to use the “Light Emitting Diode (LED)” component in Proteus simulation software. In case you have not got on through the basics of Proteus, here is...

A self-igniting candle implemented using AVR and PIC microcontrollers. This project has two variations, one using an ATTiny25, the other using a PIC12LF1822. In a series of minimalistic devices, this electronic candle periodically measures ambient light levels. Once it detects...
