## Charlieplexing 7 segment displays using Microcontroller Using Atmega

This instructable describes how to charlieplex a bunch of 7-segment led displays. Charlieplexing of discrete leds has been the topic of a few other instructables. The Charlieplexing LEDs- The theory and the How to dr ive a lot of LEDs from a few microcontroller pins comes to mind. They are both excellent and should be read by anyone that wants …

## Lampduino – an 8×8 RGB Floor Lamp Using Atmega

Lampduino is a computer-controlled free-standing floor lamp, comprised of an 8×8 RGB LED matrix. The lamp stands 45″ high and 18″ wide.  Light emanates from both sides.  It has various display modes, as well as an included editor for creating animations.  The lamp is controlled via an application running on a PC host.  The display modes include …

## LED Binary Calculator using Microcontroller ATtiny2313

You can’t calculate binary values “as is” on most handheld calculators and using the windows one is just a pain, so i decided to make my very own (binary only) calculator. This calculator supports all the basic functions like : NOT,OR,AND,XOR, addition,subtraction,multiplication,division and modulo. So join me as we are going to enter the world of ones and zeros …

## Make a 8×10 L.E.D Matrix using the Arduino and 4017 decade counter Using Atmega

In this instructable I will show you how to build a quite fancy 8 by 10 L.E.D matrix(with scrolling text and animations) using the Arduino and 4017 decade counter. This type of matrix is easy to make and program and it is a good way learn how to multiplex. I have added another part to this instructable about using …
