Intelligent LED light controller using AVR

Now a days LED light bulbs are becoming more and more popular because they have several advantages. Some of their advantages are listed below ·         Their energy (electrical) consumption is much more less ·         Their luminance is more ·         Their intensity can be varied ·         Their life time is more So if LED lights are used in place of conventional lights we can save much more electrical ene ...

Bluetooth Controlled Portable LED Display

The aim of the project is to make a portable LED display from SMD LEDs and to display the custom programmed patterns at our command. The core application of the project is to act as a portable display for event organisers or exhibitionists or consultants to make announcements at their mobile facilities. This can also be used as a novelty item in a showcase. This project is demonstrated by giving an overview ...

MultiFunction LED Game Using An ATmega32 Microcontroller

First are my answers to the Make-To-Learn Contest: What did you make? I made a multi-function LED Array Program, like my previous one with Arduino UNO, but this time I made it with an ATmega32 microcontroller. I used regular C code to program it and no Arduino was involved at all. I also added a second row of LED's to the device for a total of 14 LED's. Two buttons are used for a game, and one big button is ...

Remote Controlled POV Display Using Atmega1284

Introduction For our ECE 4760 final project, we designed and implemented a remote controlled persistence-of-vision (POV) display that is able to display multiple patterns based on remote input. The primary components of the display are a rotor and a motor. The rotor is mainly consisted of a row of LEDs and a microcontroller. The microcontroller controls LEDs. The basic theory behind POV is that if LEDs flas ...

Touchpad Figure Recognition Using Atmega644

Our project implements a touchpad input system which takes user input and converts it to a printed character. Currently, the device only recognizes the 26 letters of the alphabet, but our training system could be easily generalized to include any figure of completely arbitrary shape, including alphanumerics, punctuation, and other symbols. A stylus is used to draw the figure/character on the touchpad, and t ...

BrainMap: fNIR imaging of the brain Using Atmega644

Introduction Our project records and extracts event-related features from a 36-point relative blood-oxygen concentration sensor array from the surface of the brain. We chose this project because of a combined interest in brain-computer interfaces. In an attempt to balance cost, complexity, and sensor density, we decided to implement a NIRS-inspired system. After collecting data from the array, the results w ...

LED-Following K’NEX Car Using atmega644

Introduction In a Nutshell Our ECE 4760 final project was a car made of K'NEX that follows a LED strip. What We Did For this project we made a K’NEX car that follows a path made by a LED strip. We used two phototransistors to detect the lights from the LED, while considering ambient light. The voltage generated by the phototransistors were sent to an A-to-D converter so that we could calculate the car’s rel ...
