Arduino Duemilanove USB Board with Atmega328

Based on the Atmel ATMega328 processor the Arduino Duemilanove "2009" is a small but feature rich board that is ideal for getting started in the world of microcontrollers.

The Duemilanove easily connects to your computer via a USB cable to transfer programs 'sketches' for running on the board itself or for sharing data between the board and pc. It features 14 digital IO pins (6 can be used as PWM outputs), 6 analog inputs, USB connection, 16 MHz crystal oscillator, a power jack, reset button and ICSP header.

Power can be supplied directly from the USB cable or via the power jack from a battery or DC power supply with the Duemilanove automatically selecting the power source.

Software for programming the Duemilanove is available free from the Arduino web site and runs on Windows, Mac or Linux.

For a size comparison, the Duemilanove is shown here in the middle, with the Arduino Mega on the left and the Arduino Nano on the right.

Part of the secret to the Arduino success is that it makes microcontrollers accessible to people without previous experience. The USB support and bootloader on the Duemilanove make it easy to transfer programs to the board without any additional hardware unlike many other boards, plus the large community of enthusiests sharing program examples and hardware setup ideas makes gettings started easy.

If you are new to electronics and/or programming then I strongly recommend Limor's Arduino tutorial as an excellent intoduction.
