Compared to the old version, R3 version major changes:
1)Atmega 16U2 chip alternative 8U2. Means a higher transfer rate and memory.
2)increase the SDA and SCL interface.
1.Pin changes plus two I2C pins (SDA and SCL: next to the AREF pin, the Analog 4 and 5 copy, not the additional I2C interface), addedtwo pins, the RESET next one is IOREF, , allowing the expansion board to adapt to on-board voltage, this pin is just told to expandthe board's current on-board voltage (such as UNO is 5V, the power supply pin can be seen as copy, does not provide the level pull-up), and the other is after inactive placeholder pins.
2. More stable RESET circuit. RESET key position has changed, be moved close to the USB interface board corner, more convenient to press.
3. ATmega16U2 to replace a 8U2, this does not mean a 16K flash R3 to make your code run faster, this update for the USB interface chip, in theory, it allows the UNO can emulate USB the HID, such as the MIDI / Joystick / Keyboard.
Open circuit diagram of the original design, the development of software interface for free download, can also be in accordancewith the requirements and their modified, download the program is simple and convenient, Can simply use sensors, all kinds of electronic components connection(such as: LED lights, buzzer, buttons, photoresistance, etc), make all sorts of interesting word. Microprocessor controller(ATMEGA328), using high-speed development interface and the environment are very simple and easy to understand, very suitable for beginners to learn.

What is the Arduino?
The Arduion is a Simple I/o platform based on open source code, and use Java, such as Processing/Wiring of C language development environment, the characteristics of easy to understand. Allows you to quickly use the Arduino do interesting things.
The Arduino can be used with some electronic components such as: LED lights, buzzer, buttons, photoresistance, ect. The Arduion development environment based on the principle of open source interface, allows you to free download to use developed more amazing interactive work.
