Please see the Arduino support forum for more information about this new board revision and bootloader. Not sure which Arduino or Arduino-compatible board is right for you? I just got the new Arduino Duemilanove and Ardumoto.
How to “reset” an Arduino board? up vote 12 down vote favorite. 8. I've uploaded a sketch to an Arduino Uno whose loop is something like this: void loop(){ Serial.println('Hello World'); } So, now, I can't upload anything anymore, because the IDE says 'port already in use'. Reset the Arduino using the hardware button on the chip; Press Ctrl + U to upload your code. If unsuccessful - got to 3.

External (non- USB) power can come either from an AC- to- DC adapter (wall- wart) or battery. The adapter can be connected by plugging a 2.
Leads from a battery can be inserted in the Gnd and Vin pin headers of the POWER connector. The board can operate on an external supply of 6 to 2. If supplied with less than 7. V, however, the 5. V pin may supply less than five volts and the board may be unstable.
If using more than 1. V, the voltage regulator may overheat and damage the board. The recommended range is 7 to 1. 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 5 volts 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.
V. 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 5. V supply. 3. V3. A 3. FTDI chip. Maximum current draw is 5.

Input and Output. Each of the 1. 4 digital pins on the Duemilanove can be used as an input or output, using pin.
Mode(), digital. Write(), and digital. Read() functions. They operate at 5 volts. Each pin can provide or receive a maximum of 4. A and has an internal pull- up resistor (disconnected by default) of 2. Ohms. In addition, some pins have specialized functions. Serial: 0 (RX) and 1 (TX).
Used to receive (RX) and transmit (TX) TTL serial data. These pins are connected to the corresponding pins of the FTDI USB- to- TTL Serial chip. External Interrupts: 2 and 3. These pins can be configured to trigger an interrupt on a low value, a rising or falling edge, or a change in value. See the attach. Interrupt() function for details.
PWM: 3, 5, 6, 9, 1. Provide 8- bit PWM output with the analog. Write() function.
SPI: 1. 0 (SS), 1. MOSI), 1. 2 (MISO), 1. SCK). These pins support SPI communication using the SPI library.
LED: 1. 3. There is a built- in LED connected to digital pin 1. When the pin is HIGH value, the LED is on, when the pin is LOW, it's off. The Duemilanove has 6 analog inputs, each of which provide 1. 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 analog. Reference() function. Additionally, some pins have specialized functionality. I2. C: analog input pins A4 (SDA) and A5 (SCL).
Support I2. C (TWI) communication using the Wire library. There are a couple of other pins on the board. AREF. Reference voltage for the analog inputs. Used with analog. Reference(). Reset. Bring this line LOW to reset the microcontroller.
Typically used to add a reset button to shields which block the one on the board. See also the mapping between Arduino pins and ATmega. Communication. The Arduino Duemilanove has a number of facilities for communicating with a computer, another Arduino, or other microcontrollers. The ATmega. 16. 8 and ATmega. UART TTL (5. V) serial communication, which is available on digital pins 0 (RX) and 1 (TX).
An FTDI FT2. 32. RL 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 Arduino software includes a serial monitor which allows simple textual data to be sent to and from the Arduino 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 Software. Serial library allows for serial communication on any of the Duemilanove's digital pins. The ATmega. 16. 8 and ATmega.
I2. C (TWI) and SPI communication. The Arduino software includes a Wire library to simplify use of the I2. C bus; see the documentation for details. For SPI communication, use the SPI library. Programming. The Arduino Duemilanove can be programmed with the Arduino software (download). Select "Arduino Diecimila or Duemilanove w/ ATmega. Arduino Duemilanove w/ ATmega.
Tools > Board menu (according to the microcontroller on your board). For details, see the reference and tutorials.
The ATmega. 16. 8 or ATmega. Arduino Duemilanove comes preburned with a bootloader that allows you to upload new code to it without the use of an external hardware programmer. It communicates using the original STK5. C header files). You can also bypass the bootloader and program the microcontroller through the ICSP (In- Circuit Serial Programming) header; see these instructions for details. Automatic (Software) Reset. Rather then requiring a physical press of the reset button before an upload, the Arduino Duemilanove is designed in a way that allows it to be reset by software running on a connected computer.
One of the hardware flow control lines (DTR) of the FT2. RL is connected to the reset line of the ATmega. ATmega. 32. 8 via a 1. When this line is asserted (taken low), the reset line drops long enough to reset the chip.
The Arduino software uses this capability to allow you to upload code by simply pressing the upload button in the Arduino environment. This means that the bootloader can have a shorter timeout, as the lowering of DTR can be well- coordinated with the start of the upload. This setup has other implications. When the Duemilanove is connected to either a computer running Mac OS X or Linux, it resets each time a connection is made to it from software (via USB). For the following half- second or so, the bootloader is running on the Duemilanove. While it is programmed to ignore malformed data (i. If a sketch running on the board receives one- time configuration or other data when it first starts, make sure that the software with which it communicates waits a second after opening the connection and before sending this data.
The Duemilanove contains a trace that can be cut to disable the auto- reset. The pads on either side of the trace can be soldered together to re- enable it. It's labeled "RESET- EN". You may also be able to disable the auto- reset by connecting a 1. V to the reset line; see this forum thread for details.
USB Overcurrent Protection. The Arduino Duemilanove has a resettable polyfuse that protects your computer's USB ports from shorts and overcurrent. Although most computers provide their own internal protection, the fuse provides an extra layer of protection. If more than 5. 00 m. A is applied to the USB port, the fuse will automatically break the connection until the short or overload is removed. Physical Characteristics.
The maximum length and width of the Duemilanove PCB are 2. USB connector and power jack extending beyond the former dimension.
Three screw holes allow the board to be attached to a surface or case. Note that the distance between digital pins 7 and 8 is 1. Listen to the name.
This is how you can pronounce the board's name in proper Italian, download the sound file in the format that better suits you: WAV, OGG, MP3, FLAC, WMA.
Arduino - Boards. The Duemilanove automatically selects the appropriate power supply (USB or external power), eliminating the need for the power selection jumper found on previous boards. It also adds an easiest to cut trace for disabling the auto- reset, along with a solder jumper for re- enabling it. Note: around March 1st, 2. Duemilanove started to ship with the ATmega.
