Arduino UNO Rev3 is a micro-controller development board based on the ATmega328P used for building electronics projects. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz quartz crystal, a USB connection, a power jack, an ICSP header and a reset button. It contains everything needed to support the micro controller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.. You can tinker with your UNO without worrying too much about doing something wrong, worst case scenario you can replace the micro-controller and start over again.

Advantages:

1 completely solve the traditional UNO board win7 and win8 system is not compatible with the above instability. Especially in the pirated 64-bit WIN7 system, the official board can not be installed driver, and this version is very simple and easy to install.

2. Increase the pin socket, easy to use DuPont line.

3. Replace the 16u2, so that the cost reduced to half, consumers get the most benefits

Download the program simple and convenient. You can simply use the sensor, a variety of electronic components connected (such as: LED lights, buzzers, buttons, photoresistors, etc.), to make all kinds of interesting works.

The use of high-speed microprocessor controller (ATMEGA328), the development of user interface and environment are very simple, easy to understand, very suitable for beginners to learn.
