Quickstart Tutorial for AVR Microcontrollers

                                                                                                                                         

• The goal of this tutorial is to get you up and running as quickly as possible.
• You can get to exploring and modifying on your own without having to fiddle with hardware, software, parts, or settings.

Networked Biometric Authentication

 

• Another brilliant final year project from Cornell student.

Recommended Project 8 - LAN cable tester

• This useful DIY circuit is good for student to understand how microcontroller and networking works. 
• It has been designed by Mr.Vasilios Stergiopoulos

Programmer - USB programmer for Atmel AVR controllers (USBasp)

• One of simple design that most wanted by microcontroller player nowdays especially students.
• It is a USB in-circuit programmer for Atmel AVR controllers.
• It simply consists of an ATMega48 or an ATMega8 and a couple of passive components.
• The programmer uses a firmware-only USB driver.
• No special USB controller is needed.
  

Recommended Blog 4 - Vassilis Serasidis

• This blog is belong to Mr.Vassilis Serasidis
  
• It has many good project based on atmel microcontroller.
• Some of his interesting project is :

Tutorial 11 - Using the AVR Analog-Digital Converter

• This tutorial will show on how to do an analog-digital conversion with AVR microcontroller.
• AVR will receive data from the it's serial port.

Recommended Project 9 - Inertial GPS with an ATMega 128

• This project was conducted by the student of Cornell University.
• This project's goal is to determine the user's position with a commercial GPS system aided by MEMS accelerometers and gyroscopes.
  
• The additional MEMS sensors allow for prediction of the user's movement in between and in absence of the absolute GPS updates.

Recommended Project 7 - AVR Thermostat

• This thermostat is built around an ATMega164P and a TC1047A temperature sensor.
  
• It controls your furnace and air conditioner.
• It is not programmable, although it has a clock and is capable if some additional code were written.
• The unique feature is used of single rotary encoder, for a very simple user interface.

Tutorial 9 - Example using the two-wire interface (TWI)

• The two-wire interface consists of two signal lines named SDA (serial data) and SCL (serial clock).
• All devices participating in the bus are connected together.
• The pullups must be small enough to recharge the line capacity in short enough time compared to the desired maximal clock frequency.

Recommended Project 6 - ATmega 128 Prototyping Board

• Uses 64-pin ATmega128/1281/2561.
• USB-serial interface via FTDI FT232RL.
• Selectable power (USB/External/VTarget, external could be 5V or 3.3V).
• Selectable clock source (crystal or clock from FT232RL).
• All ports are avaiable at pinheaders.
• Direct interface to GU300 Graphical VFD's.
• Port D, E & F are laid out identical to the STK500.
• Port A, C & G are in a single header, making it possible for future memory expansion.

Recommended Project 5 - simple vga/video adapter

• Owner of this site wanted a design that would be capable of displaying at least 15x15 characters on a VGA monitor using standard VGA frequencies.
• The data itself is to be received by the microcontroller via its USART port.
  
• All using a 16 Mhz clock for the AVR.

Recommended Project 4 - Miniature Real-time Controller

• The circuit uses only three chips, a 89C2051, DS275(or MAX232), and 74LS07 open collector driver.
• The scheduler for time on/off of 6-channel output can be made by downloading from PC and saved into onchip RAM.
• Each output provides a 20mA sinking suitable for driving a homemade opto-triac or big solid-state relay for heavy load.

Recommended Project 3 - LCD-Clock

• This is yet another DIY clock.
• An Atmel AVR controller is used to drive a text-mode LCD to show the time in big letters.
• The letters are drawn with user-defined characters.
• The AVR's main clock is the internal R/C-oscillator.
• The code is written in C using avr-gcc with the avr-libc.
  

Recommended Project 2 - 16x24 RGB LED Array

• This project is an array of LEDs.
• 35 inches wide by 58 inches tall.
• The LEDs will be RGB.

Recommended Project 1 - Programmable path navigator Robot

• The project deals with the design and development of the mechanical, hardware, embedded software and the path feeding aspects of the robot.
• Fully functional as wireless robot.
• Path to be traced is programmed with the help of an interactive user interface in Matlab environment.
