Tarjeta De Control Arduino Duemilanove Atmega168

The Kingduino Duemilanove (it means 2009 in Italian!) is a micro-controller board based on the ATmega168 or 328.

It has 14 digital input/output pins (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.
The board contains everything needed to support the micro-controller and simply needs to be connected to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.

The board can operate on an external supply of 6 to 20 volts. If supplied with less than 7V, however, the 5V pin may supply less than five volts and the board may be unstable. If using more than 12V, the voltage regulator may overheat and damage the board. The recommended range is 7 to 12 volts.

The power pins are as follows:
VIN: The input voltage to the Arduino board when it's using an external power source (as opposed to 5V from the USB connection or other regulated power source). You can supply voltage through this pin, or, if supplying voltage via the power jack, access it through this pin.
5V: The regulated power supply used to power the microcontroller and other components on the board. This can come either from VIN via an on-board regulator, or be supplied by USB or another regulated 5V supply.
3V3: A 3.3V supply generated by the on-board FTDI chip. Maximum current draw is 50 mA.
GND: Ground pins.

Each of the 14 digital pins on the Duemilanove can be used as an input or output, using pinMode, digitalWrite, and digitalRead functions. They operate at 5 volts. Each pin can provide or receive a maximum of 40 mA and has an internal pull-up resistor (disconnected by default) of 20-50 kOhms. In addition, some pins have specialized functions. (Details in files tab below.)

The Duemilanove has 6 analog inputs, each of which provide 10 bits of resolution (i.e. 1024 different values). By default, they measure from ground to 5 volts, though is it possible to change the upper end of their range using the AREF pin and the analogReference function. Additionally, some pins have specialized functionality. (Details in files tab below.)

A  number of communication  facilities are provided for connecting the  Duemilanove  to a computer, another Kingduino board, or other microcontrollers. The ATmega168 and ATmega328 provide UART TTL (5V) serial communication, which is available on digital pins 0 (RX) and 1 (TX).

An FTDI FT232RL on the board channels this serial communication over USB and the FTDI drivers (included with Windows version of the Arduino software) provide a virtual com port to software on the computer. The Kingduino software includes a serial monitor which allows simple textual data to be sent to and from the Kingduino board. The RX and TX LEDs on the board will flash when data is being transmitted via the FTDI chip and USB connection to the computer (but not for serial communication on pins 0 and 1).

A re-settable fuse to provide additional protection for your computer ports from shorts and overcurrent. If more than 500 mA is applied to the USB port, the fuse will automatically break the connection until the short or overload is removed.
