Arduino Uno

[Karl W4KRL]

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.

"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."
