The Arduino 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, etc. The Arduino development environment based on the principle of open source interface, allows you to free download to use developed more amazing interactive work.
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.
Open circuit diagram of the original design, the development of software interface for free download, can also be in accordance with 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 work.Microprocessor controller (ATMEGA328), using high-speed development interface and the environment are very simple and easy to understand, very suitable for beginners to learn.
