Markov Music Box

markov summary Traditional music boxes play one or two tunes very well, but are not very interactive. Put differently, they have a high quality of synthesis, but a fixed-pattern note sequencer and fixed tonal quality. I wanted to build a device which would play an interesting music-like note sequence, which constantly changed and evolved, with settable timbre, tempo, and beat. To synthesize nice sounding mu ...

Arduino atmega644/1284 clone

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 be able to connect every existing shields. Personally I use the ethernet shield to communicat ...

Digital Reversi board using Atmega644

Introduction For our final project in ECE 4760, we designed and implemented a Reversi board consisting of hardware, a microcontroller, and a touch screen. Sixty-four bicolor (red and green) LEDs were implemented as the black and white pieces of the game. Players could simply light up a LED (place a piece) by touching the touch screen in the position right above the corresponding LED. Other LEDs would be fli ...

Audio Spectrum Analyzer Using Atmega644

Our ECE 4760 final project was an audio spectrum analyzer that would display a histogram-style visualization of an audio signal. We were able to successfully display the frequency spectrum content of an audio signal in real-time using a black and white histogram visualization with bins arranged from left to right corresponding to low to high frequency ranges using a system based upon two Atmel Mega1284 micr ...

Virtual Archery Using Atmega644

Introduction We decided to create a virtual archery game for our ECE 4760 final project. This game consists of an ATmega1284P microcontroller, a TV for display, and multiple pieces of hardware. All of these devices communicate together to simulate a three-round game of archery with a target that is 20 feet away from the user. The ATmega1284P microcontroller uses its internal analog-to-digital converter (ADC ...

Alphanumeric Optical Endec Transceiver Using Atmega644

Introduction Our goal in this project was to build a pair of high-speed transceivers that could encode and decode optical signals modulated using Morse code conventions. The project involved a few interesting challenges that we believed would be interesting to tackle. Interfacing a camera with a microcontroller is a difficult thing to do, due to the limited memory capabilities of most microcontrollers. Beca ...

GPS and compass guided car Using Atmega644

For our final project, we built a self-driving car that takes in inputs for a final destination and drives itself from its initial location to the final destination. The idea for this final project requires an LCD to display the location that the car is already at and allows a user to input coordinates for where he or she would like the car to drive itself to. By using a GPS receiver, the car can track its ...
