1. What is the difference between Arduino Duemilanove and Diecimila?
The Arduino Duemilanove and Diecimila are two early models of the Arduino board. While they are similar in many ways, there are a few key differences between them.
The main difference between the Arduino Duemilanove and Diecimila is in their USB connectivity. The Duemilanove uses an FTDI USB-to-serial converter chip, while the Diecimila uses an ATmega8U2 microcontroller with built-in USB support. This means that the Duemilanove requires an additional driver to be installed on the computer, while the Diecimila is recognized as a standard USB device.
Another difference is the location of the power jack. The Duemilanove has a power jack on the side of the board, while the Diecimila has a power jack on the end of the board. This can make a difference in how the board is mounted in a project enclosure.
Finally, the Duemilanove has a slightly larger memory capacity than the Diecimila. The Duemilanove has 32 KB of flash memory, while the Diecimila has 16 KB of flash memory.
2. What is the difference between Arduino Uno and Duemilanove?
Arduino Uno and Duemilanove are both popular microcontroller boards, but there are some key differences between them.
The main difference between the Arduino Uno and Duemilanove is the microcontroller used on the board. The Uno uses an ATmega328 microcontroller, while the Duemilanove uses an ATmega168 or ATmega328 microcontroller. The ATmega328 microcontroller used on the Uno has more flash memory (32 KB) and RAM (2 KB) than the ATmega168 microcontroller used on the Duemilanove (16 KB of flash memory and 1 KB of RAM).
Another difference is that the Uno has a different USB-to-serial converter chip than the Duemilanove. The Uno uses an ATmega16U2 microcontroller with built-in USB support, while the Duemilanove uses an FTDI USB-to-serial converter chip. This means that the Uno can appear as a USB keyboard or mouse, while the Duemilanove requires an additional driver to be installed on the computer.
The Uno also has a few additional features that the Duemilanove does not have. For example, the Uno has an extra hardware UART (serial communication) port, a reset button that can be used to restart the board, and more input/output pins than the Duemilanove.
