Arduino Duemilanove mega 328Introduction The Arduino Duemilanove is a microcontroller board based on the ATmega328 (datasheet). It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz crystal oscillator, 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. specifications MicrocontrollerATmega328Operating Voltage5VInput Voltage (recommended)7-12VInput Voltage (limits)6-20VDigital I/O Pins14 (of which 6 provide PWM output)Analog Input Pins6DC Current per I/O Pin40 mAFlash Memory32 KB of which 2KB used by bootloaderSRAM1KBEEPROM512 bytesClock Speed16 MHz application video PS2 joystick functional demonstration http://v.youku.com/v_show/id_XMTc0ODk0MjUy.html
