One of the important features in today’s modern microcontroller is the capability of converting the analog signal to the digital signal. This feature allows us to process the analog world easily such as temperature, humidity, light intensity, distance, etc; which usually captured by electronics sensor and represent it on the change of voltage level. In […]

One of the frustrating part in learning AVR microcontroller for the beginners is the AVR microcontroller programmer. The question is how to program my AVR mircrocontroller; actually if you googling on the internet and search for AVR ISP Programmer there are plenty information; start from simply using your PC parallel port to the sophisticated Atmel

Introduction The main idea for our project was to implement an inexpensive solution to the current CU Snake Arm motor-driving system by using a Mega644 microcontroller instead of multiple 3-Amp motor controllers as the snake arm was originally intended to be driven. Since we used DC motors, we implemented a PID control algorithm that determines

Introduction We set out to make an easy to interact with, highly custimizable POV display. In deciding on a project we looked for a challenge that would have a good mix of hardware and software problems. We ended up primarily concentrating on looking at unusual display technologies and decided that a persistence of vision(POV) display

Introduction The purpose of this project is to create a Scheme interpreter using C language and Mega32 microprocessor. Using limited resource and memory in the microprocessor, the interpreter should function and work for basic Scheme commands. The main target of the project is to use the memory of the microprocessor as fully as possible to

The goal of this project was to develop a system capable of emulating an Apple II personal computer. This project attempted to reconstruct a functional Apple II emulated on Atmel ATmega32 processors. Due to time constraints, a fully functional Apple II was not produced; however, a working emulated 6502 processor, memory subsystem, and partial GPU

The project which we are presenting is not the project we presented in our proposal. We initially planned to build a WWVB time-code receiver, which would demodulate a 60 kHz signal and extract an extremely precise time according to the National Institute of Standards and Technology (NIST). Unfortunately, due to a weak signal and noise

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 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
