Our goal for this project was to build an OBD-II compliant device that would communicate with any OBD-II enabled car and read back real time data as well as perform basic performance testing and diagnostics. If you’ve ever had to take your car into the shop because of the dreaded “Check Engine” light, you can […]

ADC is an electronics device that converts the analog signals to digital number proportional to the magnitude of voltage. The ADC chips like ADC0804, ADC0809 etc., give 8-bit digital output. The controller device needs eight pins to receive the 8-bit data (For more details about ADC refer to Using Inbuilt ADC of AVR). Some applications need higher

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

I. Introduction Today, the rising cost of energy and social trend of “going green” has put increasing pressure on commercial property owners to improve the efficiency of their investments. There is good reason for this, too. In the State of California, office buildings represent the single largest user of energy in the commercial sector (Efficiency
Introduction “Our project implements the game, Reversi, on TV with a smart artificial intelligence and a host of other features!” It’s our childhood game. We were so excited when we found out that we can actually build it for our 476 final project. We looked at the websites for various design of the game setup

The purpose of this project was to take a traditional remote controlled car and create our own control mechanisms. To control the car, we used a dual-axis accelerometer and LEDs (light emitting diodes) configured as photo-detectors. The control mechanism was selected using a single pole dual throw (spdt) switch was wired in a single pole

Introduction Our project is a wireframe 3D video game based on the classic Atari arcade game, Battlezone (Copyright Atari Corp, 1980). For those that have never heard of the game, Battlezone is a game in which the player maneuvers a tank through a flat environment, shooting and destroying enemy tanks while taking advantage of

Kang Li(kl694) and Zhenxuan Qiu(zq39) For our ECE 4760 final projec, we built a pair of toy “cat ears” using electroencephalography (EEG) with the AVR microcontroller. The basic function of it is that it can change the gesture of the “Ears” based on the participant’s emotion. The user doesn’t need to do anything except for

Introduction: But now I can do this very easily by a simple digital signal processing using a microcontroller. It’s concept is very simple, ie we need to apply a proper delayed feedback in digital samples with in a circular buffer. I did this using an atmega32 microcontroller and it worked fine. This is simple but really an interesting project.
