This project aims to automate the process of taking attendance on pen and paper and prevent any fraudulent entry. It uses RFID tags to record attendance. Each student is assigned a unique tag, which he/she is required to swipe over the reader to give his/her attendance. This system benefits both the teacher and student as its quick […]

Multiplexing LEDs can be tricky, but we’re working with RGB LEDs, so think of each RGB as three individual LEDs. For an 8 x 8 matrix, that is 192 total LEDs on a single matrix. Even though there are only 32 connection pins, it is still possible to individually control the color and brightness of

In this article I will describe how to interface a Ultrasonic Range Finder Module with a AVR ATmega8 microcontroller. I will provide a HEX file which you can burn into your ATmega8 directly to quickly test this whole setup. Ultrasonic range finder modules helps find the exact distance to an object. This can have vast

A GSM/GPRS Module like SIM300 can be used for any embedded application that requires a long range communication, like a robot in Chennai controlled by a person sitting in New Delhi! Or simply a water pump in a rice field turned on in the morning by a farmer sitting in his house few kilometers away! You have

If you have played games on console you must be knowing what a joystick is. In games a joystick is generally used to control the motion of character or a vehicle (like plane or car). Joystick give a very realistic two dimensional control! Joystick are also used to control the motion of real objects like

If you want to use an inexpensive ATmega168 or ATmega328p for your project, but you want the simplicity of the arduino code and codebender, this tutorial will guide you through! A brand new ATmega microcontroller does not come preconfigured to use with Arduino code. So to use one of these you normally need a high

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

it is very difficult to bootload Atmega chips when you don’t have proper knowledge about device signature ! each chips are associated with its own Signature.at the beginning I found very difficult in uploading bootloader file to Atmega 328pu and Atmega 328p-pu , although their are many different methods are already available in Internet ,it

This project is about to DIY an Arduino board wth an ATMEGA644P or 1284P to have more INPUTS/OUTPUTS than on the atmega328P. You can buy an arduino mega but it’s more expensive. The microcontrollers will be bootloaded with Sanguino and the project seems to be like another one called CALUNIUM. On this clone you will

In this project, a device will be designed that will read analog data from any analog sensor and will send the digitized form of that data to a personal computer on USB interface. On PC, a desktop application will store the data in an excel spreadsheet therefore performing the data logging. For this, the device
