Introduction To align with the current trend of incorporating networking capabilities into everyday devices, our project incorporates a webpage interface for the Atmel AVR microcontroller. Initially, one of our main objectives was to develop a low-level network interface for the Atmel device, which involved controlling an ISA network card (as seen in the eAVR Project) …
Hi friends, here is my experiment with i2c bus for interfacing serial EEPROM (24C256) and RTC (DS1307) using AVR microcontroller ATmega128. The circuit is also provided with an RS232 port for connecting with PC to send commands for reading/writing EEPROM or setting date/time in RTC (Click on images to enlarge them). Communication with PC is …

Learn how to turn your Arduino into an AVR In System Programmer. This will allow you to burn bootloaders onto new chips or program AVRs without a bootloader. Step 1: Materials To begin you will need: * Arduino (I will be using the Uno) * AVR Microcontroller (This tutorial will cover the ATtiny85 & ATmega644) …
This instructable will show you how to easily modify a readily available plastic case to hold and protect your AVR Dragon PCB. Atmel promotes their AVR Dragon as a low cost development product tool for use with their AVR microcrontollers. While the product does come in a fancy red cardboard box, unlike all the other …

Description The PCF8583 is a clock/calendar circuit based on a 2048-bit static CMOS RAM organized as 256 words by 8 bits. Addresses and data are transferred serially via the two-line bidirectional I2C-bus. The built-in word address register is incremented automatically after each written or read data byte. Address pin A0 is used for programming the …

Description The TC77 is a digital temperature sensor with a Serial Peripheral Interface. Temperature data is converted from the internal thermal sensing element and made available at anytime as a 13-bit two’s compliment digital word. Communication with the TC77 is accomplished via a SPI and MICROWIRE compatible interface. It has a 12-bit plus sign temperature …
In this project i have interfaced an GPS with AVR microcontroller, the ATtiny2313 gets the location from the GPS and display it over the LCD display. This project also have the feature of marking a place with its name. For entering the Name of the place i have used the PC-AT Keyboard. At starting the …
This projects gives you a simple wav player with help of the MMC card connected to ATmega32. You can use any AVR microcontroller. The MMC card works on 3.3v so a 3.3v regulator is used and the 5v to 3.3v level conversion is done by the combination of resistors. The LF33CV is used for the …
