What is the best baud rate?
Other “standard” baud are 1200, 2400, 4800, 19200, 38400, 57600, and 115200. The higher a baud rate goes, the faster data is sent/received, but there are limits to how fast data can be transferred. You usually won’t see speeds exceeding 115200 – that’s fast for most microcontrollers.
What is duemilanove?
The Arduino Duemilanove (“2009”) is a microcontroller board based on the ATmega168 (datasheet) or 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.
What is the difference between ATmega168 and ATmega328?
The differences between the 328 and the 168 are pretty minor and you should see no differences except for having double the programming space!
What is the Duemilanove?
“Duemilanove” means 2009 in Italian and is named after the year of its release. The Duemilanove is the latest in a series of USB Arduino boards; for a comparison with previous versions, see the index of Arduino boards . EAGLE files: arduino-duemilanove-reference-design.zip
How many analog inputs does the Duemilanove have?
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:
What is Arduino Duemilanove?
Arduino Duemilanove. Overview. The Arduino Duemilanove (“2009”) is a microcontroller board based on the ATmega168 (datasheet) or ATmega328 (datasheet).

Is the bootloader running on the Duemilanove?
For the following half-second or so, the bootloader is running on the Duemilanove. While it is programmed to ignore malformed data (i.e. anything besides an upload of new code), it will intercept the first few bytes of data sent to the board after a connection is opened.
