Micro Center in Fairfax has the Arduino Uno rev. 3 board for $19.95. Here is
a great way to get started with Arduino. Spark Fun and Maker Shed sell this
for $30 to $35.

Microcontroller                 ATmega328

Operating Voltage           5V

Input Voltage (recommended) 7-12V

Input Voltage (limits)     6-20V

Digital I/O Pins                   14 (of which 6 provide PWM output)

Analog Input Pins             6

DC Current per I/O Pin   40 mA

DC Current for 3.3V Pin 50 mA

Flash Memory                   32 KB (ATmega328) of which 0.5 KB used by

SRAM                                    2 KB (ATmega328)

EEPROM                              1 KB (ATmega328)

Clock Speed                       16 MHz


"The Arduino Uno is a microcontroller board based on the ATmega328. It has
14 digital input/output pins (of which 6 can be used as PWM outputs), 6
analog inputs, a 16 MHz ceramic resonator, a USB connection, a power jack,
an ICSP header, and a reset button. It contains everything needed to support
the microcontroller; simply connect it to a computer with a USB cable or
power it with a AC-to-DC adapter or battery to get started."



Nice comparison of the Uno with earlier versions:

Some good ham projects using the Arduino:
