This is the new Arduino Uno R3. Notwithstanding every one of the highlights of the past board, the Uno now utilizes an ATmega16U2 rather than the 8U2 found on the Uno (or the FTDI found on past ages). This takes into account speedier exchange rates and more memory. No drivers required for Linux or Mac (inf petition for Windows is required and incorporated into the Arduino IDE), and the capacity to have the Uno appear as a console, mouse, joystick, and so on.
Arduino is an open-source physical figuring stage in view of a basic I/o board and an advancement domain that actualizes the Processing/Wiring dialect. Arduino can be utilized to create remain solitary intuitive questions or can be associated with software on your computer (e.g. Streak, Processing, MaxMSP). The open-source IDE can be downloaded for nothing (at present for Mac OS X, Windows, and Linux).
The Uno R3 likewise includes SDA and SCL pins alongside the AREF. What's more, there are two new pins set close to the RESET pin. One is the IOREF that enable the shields to adjust to the voltage gave from the board. The other is a not associated and is held for future purposes. The Uno R3 works with every single existing shield however can adjust to new shields which utilize these extra pins.
