描述

Description: Arduino is a Simple i/o platform based on the open source code and it is easy to understand and use Processing/Wiring development environment similar to Java to let you quickly make out useful works. Arduino can be used with some electronic components, like the LED lamp, buzzer, button, photosensitive resistance and so on. The interface of Arduino development environment is based on the open source code principle and it can be downloaded and used for free to develop more amazing interactive works. Feature: You can open the original designal circuit and download the interface of development software for free. You can also modify them according to your demand and the downloading program is easy and convenient. You can simply use sensors, and connect a variety of electronic components (such as: the LED lamp, buzzer, button, photosensitive resistance.), making all sorts of interesting works. The Development interface and the environment of (ATMEGA328) are very simple and easy to understand and it is very suitable for beginners learning.
