As government agencies recommend greater consumption of seafood for its health benefits, a new analysis led by researchers from the Johns Hopkins Center for a Livable Future urges medical and public health professionals to consider the environmental and health impact of seafood sourcing, particularly aquaculture, or the farming of fish, shellfish and crustaceans.

Objective: To design a debugger that is capable of tracing AT90S1200 user programs while the micro-controller is attached to external peripherals. The debugger will be able to display I/O activities, and dump the values of the registers. Parts Required: Atmel STK-200 starter kit (kit includes a single AT90S8515 micro-controller), Inter x86 compatible PC (required for […]

Freescale Semiconductor introduced the MM9Z1J638, AEC-Q100 qualified intelligent battery sensors with three measurement channels, a 16/32-bit MCU and a CAN protocol module in one 7 x 7 mm 48-pin QFN package. The market this product serves is quite diversified with 12 V lead acid batteries, 14 V Li-Ion batteries, Lead acid multi-batteries, HV battery junction […]

We tried all kinds of ways to get the Arduino IDE to compile and program our ATMega128 chips that we’d so carefully soldered onto our breakout boards. Steve spent longer than could be reasonably expected, hammering away, determined to make progress. In fact, he got so far as to get Arduino 022 to compile some […]

Introduction The design philosophy behind the JI1000 is a simple, yet powerful microcontroller based mobile security system. At the heart of the JI1000 is the Atmel AT90S4414 8-bit RISC microcontroller. We used the 4414 for this design because a microcontroller is well-suited for a security system. The basic control functions for our system include monitoring […]

Soundbyte If you ever thought you couldn�t control things with your eyes, think again � here�s the game Snake that allows 4 modes of multi-level game play with buttons or with your eyes, using electro-ocular potential. Project Summary While brainstorming for a 476 final project that would be biomedical engineering-related, we stumbled upon the idea […]

Introduction For our final project, we used an Atmel AT90S8535 microprocessor to create a hangman game. The letters are displayed on a 16-character LCD, and are input (“guessed”) using a 16-button keypad. The 8 LED’s on the Atmel development board are used as our “hanging man” – one lights up for each wrong guess. We […]

Introduction Many of the simpler electronic games of the past decade can be easily programmed on the AVR microcontrollers we are using this semester, using only the lights and switches available on the evaluation boards. For our final project we programmed the game Simon using the AT90S8535 microcontroller chip and corresponding evaluation board. This is […]

Introduction The goal of our final project was to design a thermostat using an Atmel AT90S8535 microcontroller. The thermostat was to compute the current temperature once per second and then send an on/off signal to a heating device which would then regulate the temperature to a desired target temperature. In addition, the thermostat was required […]

introduction An article in Technology Review (March 2005) showcasing several cool and futuristic inventions developed at the MIT Media Lab was the source of inspiration behind our project idea. Among the various projects highlighted were two robotic flowers developed by the Robotic Life group, one of which could sense heat and orient itself toward people. […]
