Standalone Atmega328

We all have a deep fondness to our Arduino with its familiar shades of blue/green, but the time has come to explore other project options. One that involve fewer pieces, fewer parts, and fewer dollars. Building a standalone Atmega328 is far simpler than you might have imagined and can open up a wide range of of new project possibilities. Step 1: Materials: The shopping list contains parts that are entirely ...

Laser Tag with wireless logging using Atmega644

Introduction "A new spin on Laser Tag with Wireless Real-Time Updates" For our ECE 4760 final project, we designed and built our own laser tag system. We included many traditional laser tag features, but then added our own 4760 twist. For the purposes of a prototype for this class, we only created enough equipment for two players. This however could be easily scaled by building more blasters in the future. ...

Smart Trash system Using Atmega644

Introduction top For our final project, we have designed and built a 'proof of concept' prototype for Project Green Stations, an externally funded student group with the following mission statement: Project Green Stations is all about changing the way people see the environment. Imagine the go-green movement as a brand. Solar panels, Toyota Priuses, and waste receptacles are all points of interaction with y ...

Voice decoder for vowels Using Atmega644

Introduction In our final project, we created a smart voice decoder system that is capable of recognizing vowels in human speech. The audio input is sampled through a microphone/amplifier circuit and analyzed in real time using the Mega644 MCU. The user can record and analyze his/her speech using both hardware buttons and custom commands through PuTTY. In addition, the final product also supports a simple v ...

Step Sequencer Drum Machine Using Atmega644

Overview [top] As avid audiophiles, we wanted to apply our newly acquired knowledge of microcontrollers to build a fun consumer electronic device. Our project is a step sequencer drum machine. The user is able to program a 16-step percussion pattern using one of a wide range of percussion instruments on each of six different tracks. The user toggles between different tracks and different instruments and adj ...

Acoustic Data Modem Using Atmega644

Introduction For our final design project, we designed and built a prototype acoustic modem to serve as a physical transport layer for digital communications. It converts between a digital communications scheme (RS-232) and an acoustically coupled communications scheme of our own design. Our project consists of a pair of such modems to operate as transmit/receive pairs and supports duplex communications. Al ...
