SainSmart UNO R3 Starter Kit For Arduino
Arduino Introduction
Overview
What is Arduino?
Arduino is a tool for making computers that can sense and control more of the physical world
than your desktop computer. It's an open-source physical computing platform based on a simple
microcontroller board, and a development environment for writing software for the board.
Arduino can be used to develop interactive objects, taking inputs from a variety of switches or
sensors, and controlling a variety of lights, motors, and other physical outputs. Arduino projects
can be stand-alone, or they can be communicated with software running on your computer (e.g.
Flash, Processing, MaxMSP.) The boards can be assembled by hand or purchased preassembled;
the open-source IDE can be downloaded for free.
The Arduino programming language is an implementation of Wiring, a similar physical computing
platform, which is based on the Processing multimedia programming environment.
Feature
Schematic design of the open source development interface free download, and also
according to the needs of their own changes
Download the program is simple and convenient.
Simply with the sensor, a wide range of electronic components connection (such as: LED
light, buzzer, keypad, photoresistor, etc.), make all sorts of interesting things.
Using the high-speed micro-processing controller (ATMEGA328).
The development of language and development environment is very simple, easy to
understand, very suitable for beginners to learn.
