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...

In this tutorial you will learn how to drive a 8x8 led matrix using MAX7219 display driver IC. In this instructable I'm going to show you how to Interface with LED matrix using an Arduino and MAX7219 IC, this project can be used to make low resolution images using LEDs. This project...

Dark activated LED light is a simple project which operates a LED when the light falling on the LDR goes below a set point.  The circuit is built using LM393 comparator, LDR as light sensor, preset (potentiometer) for sensitivity adjustment, transistor to drive the LED. The project...

Tom blogged about his WiFi/Browser controlled RGB LED project: Features Simple hardware, using pre-fabricated modules Controls an RGB LED via any recent browser, any operating system WiFi credentials can be configured via browser Software is written as an Arduino...

In this project, you’re going to build a web server with an ESP8266 to remotely control an RGB LED. This project is called ESP8266 RGB Color Picker. ESP8266 RGB Color Picker -...

Mini (1.44'' x 0.94'' or 24mm x 37mm) 8X16 RGB LED Array. 128 RGB LEDs with three LED chip each gives 384. For this project I designed two PCBs. A control PCB and a LED PCB. My goal was to fit them both in a small panel inside a 5x5 cm square to use cheap Chinese Manufacturing...
