In this tutorial we are going to interface a joystick module with atmega8 microcontroller. A JOY STICK is an input module used for communication. It basically makes easy the user machine communication. A joystick is shown in below figure. The joystick module has two axis – one is horizontal and other is vertical. Each axis of joystick is […]
In this session we are going to design an 8×8 LED display with 8×8 LED matrix and ATmega8 microcontroller, which can show alphabets or names. A 8×8 LED matrix contains 64 LED (Light Emitting Diodes) which are arranged in the form of a matrix, hence the name LED matrix. These matrixes can be made by circuiting 64

In this tutorial we are going to design an 8×8 LED Matrix Scrolling Display using ATMEGA32, which will show scrolling alphabets. 8×8 LED Matrix contains 64 LEDs (Light Emitting Diodes) which are arranged in the form of a matrix, hence the name is LED matrix. We are going to make this Matrix by soldering 64 LEDs on

Badges are amazing things. Better when you make your own. I was about to attend the 1st MakerFest at NID, Ahmedabad and thought of taking something unique to the event. Badge was a great option and suited the maker theme of the event. So, sitting down with a pen and paper i drew what it
A while ago I found some blog posts explaining how to use a LED matrix as a pendant (http://hackaday.com/2013/01/10/8×8-led-matrix-pendant-sealed-in-a-block-of-epoxy/ and https://sites.google.com/site/tinymatrix/ ). The 8×8 matrix pendant looked cool, but it was missing detailed information on which parts to use and how to solder everything together. With help from a friend, Uriel Guy, we managed to

In the Internet of Things movement, people across the globe are connecting their stuff – TVs, pets, even houseplants – to the internet and transmitting all sorts of data. If you’re going to be a part of that movement, or want to dabble in creative prototyping on a budget, it’s important to get to know
This is a good project for beginners. It is easy to build.This running LED light uses seven bicolor led’s red and yellow, they light up in a pattern that can be made within the program code.The program code is written in assembler. ATMELs AVR STUDIO is used to write the program. The project uses the
his project shows the temperature on a three digit 7-segment display, it measures the temperature from -9.5 to 99 degrees Celcius in 0.5 C steps, or from 0 to 210 degrees Fahrenheit in 1.0 degrees steps. Because of the LED display the temperature is also readable in the dark. This project is available pre-assembled and
Page 1 of 4 An RGB LED is a LED which has three LED’s integrated in one packaging. These LED’s have the colors Red, Green, and Blue. The RGB LED used here is a hyperflux LED with common cathode, which can draw 20mA current. Such a LED costs about 2€. With these three colours you can
Schematic and build Below is the schematic of the LED VU meter. The circuit is builds with the ATMega328 board an two LED boards connected to it. You can also build it on a breadboard. For more detail: LED VU meter
