Introduction to Arduino.
Arduino is the tool used together with computer to cause the computer can receive
external signal and also make computer can send signal to control the external device
more effective than using computer alone.
The Arduino board is designed from single-chip microcontroller (Normally use AVR 8-bit
microcontrooler).It also have a software used for writing the program or command to
control the board.
Arduino can be adapted to make an intelligent tools such as the tool that can receive the
signal from switch or sensor,tool for control the lamp or motor,tool for communicate with
wireless device etc.Arduino project can work alone or work joinly with PC (work by
interaction with the program that run on PC).The board can be assembled by yourself or
buy the ready-to-use development board from vendor.It is the open hardware so everyone
are able to clone it but must use other label name.The purpose of Arduino project is to
make the low cost and easy-to-use tools for hobbyists who want to develop their simple embedded
project and don’t want to use the expensive microcontroller with complicated development
environment.
Why Arduino??
In market of microncontroller, their are many choice such as Parallax Basic
Stamp,Funnel,Pidgets,MIT’s Handyboard and from other vendors that have characteristics
similar to Arduino (That is making the board easy for develop project and underline on
programming for control the microcontroller).But Arduino has an obvious different points
from the others as you can see below…
1. Board is not expensive when compare with other boards.The cheapest Arduino board can
be obtained by making it ourselve.If you want to buy it,I think ready-to-use Arduino
board is not over $30.
2.The software used for develop Arduino can work on many platforms (Windows,Macintosh OSX
and Linux).It is easy to use for beginner and have fully capability with respect to the
professional developer’s requirement.
3.Arduino software was published as an open source.You can modify the software to
increase its capability via C++ library.If you want to deeply study its software, you can
go across to use AVR C (AVR C is prototype of Arduino) and you can add AVR-C code
directly if you want.
4.Arduino is open circuit (Open Hardware).It use the microcontroller from Atmel (ATMEGA8
and ATMEGA168).You can extend the hardware according to your demand.The circuit of Arduino board was published under the Creative Commons License so you can study about its machanism for free.
