Arduino Duemilanove 2009 AVR Mega168Introduction What is Arduino? Arduino is an open-source physical computing platform based on a simple i/o board and a development environment that implements the Processing/Wiring language. Arduino can be used to develop stand-alone interactive objects or can be connected to software on your computer (e.g. Flash, Processing, MaxMSP). The open-source IDE can be downloaded for free (currently for Mac OS X, Windows, and Linux). specifications Microcontroller ATmega168 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 16 KB (of which 2 KB used by bootloader) SRAM 1 KB EEPROM 512 bytes Clock Speed 16 MHz application videos PS2 joystick functional demonstration http://v.youku.com/v_show/id_XMTc0ODk0MjUy.html
