Thank you for taking the time to explore the avrprojects website. Here you can find projects about AVR 8-bit microcontrollers. We hope you`ll find these pages both educational as inspiring.

This board is a development board on which you can build your projects. It is suited for educational use, experiments or prototyping. The board uses the ATTiny2313 microcontroller with a 20Mhz clock. The board contains the ISP 10-pin connector for in circuit serial programming. It has also a push button reset switch. It has 15 digital I/O ports with 4 PWM output channels.

The ATMega328 board is a microcontroller board based on the ATmega328, The board contains everything needed to support the microcontroller. The board need 5VDC to power it. Simply connect the power connector to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started. You can program it with the ICSP connection. The ATMega microcontroller boards can be programmed with a serial port programmer,  parallel port programmer or USB port programmer.

This is a Dot Matrix Scrolling Sign. A Dot Matrix Display has an 5x7 led matrix with 5 columns and 7 rows. The display is controlled by the ATMega328 microcontroller board. The rows are controlled by PORTB of the microcontroller, while PORTD puts the data on the columns to make the characters. The Dot matrix display used here is the LTR-747HR and is 0.7 inch (17.8mm) high.

In this project a LED is used to mimic a flickering candle as closely as possible. When using a LED to behave like a candle, it may not be possible to sway the flame, but what can be achieved is the random variation of intensity.

This project is based on the timer/counter 0 example. It shows time, date and temparature on 7 segment displays. Instead of the LCD display the time is shown on a four digit 7 segment display with common cathode. The date and temparature is shown on a 7 segment LED display with comon anode.

In this projects 8 different colors are displayed with the use of a RGB LED. The microcontroller that is used is the ATMega8.
