Introduction: For our final project, we decided to enhance the controls of a Hummer RC truck. Our main objective was to demonstrate that an Atmel microcontroller together with basic hardware building blocks can replace all of the car’s original circuitry. Improving the RC truck’s handling involved adding analog control over steering and speed. The original

Introduction In the recent years, the MPEG Layer III (MP3) music compression format has become an extremely popular choice for digital audio compression. Its high compression ratio, and near CD quality sound make it a logical choice for storing and distributing music – especially over the internet, where space and bandwidth are important considerations. As

INTRODUCTION As technology develops, computers are making people’s lives progressively easier and safer. Someday they will be able to drive automobiles, resulting in reduced deaths and accidents. We decided to make a prototype of a self controlled car. We started with a Hot Shot II radio control car and stripped out the radio receiver. Then

Introduction The goal of this project is to design an algorithm for a real-time digital guitar tuner and implement it using an Atmel AT90S8535 microcontroller. Each of the six strings of a guitar has a unique fundamental frequency, and our goal is to measure this frequency and compare it to the correct frequency. This project

Introduction: Our final project code calls for the implementation of an amusement game often bannered as “Test-Your-Strength” or less accurately (but more commonly) known as “Whack-a-Mole.” Our machine is in essence a miniturized version of what can be found in most theme parks across the world. Its construction involves a spring load plastic cap to

Introduction: One of the newest and fastest growing additions to the digital age in the 1990s has been the handheld personal computer. Given a little flash memory and a good LCD, anything is possible and commercial products like the 3Com PalmPilot� and IBM Workpad� are flourishing. But as these products expand their functionality so does
Introduction For our final project, we set out to write a Controller for the classic toy, the Etch-A-Sketch. What this basically means, is that we use an Atmel micro controller to control two stepper motors connected to the knobs of the Etch-A-Sketch. Thus, an order by the chip to the motors would cause different angled

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

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
