An Arduino is an open-source microcontroller development board. In plain English, you can use the Arduino to read sensors and control things like motors and lights. This allows you to upload programs to this board which can then interact with things in the real world. With this, you can make devices which respond and react to the world at large.
For instance, you can read a humidity sensor connected to a potted plant and turn on an automatic watering system if it gets too dry. Or, you can make a stand-alone chat server which is plugged into your internet router. Or, you can have it tweet every time your cat passes through a pet door. Or, you can have it start a pot of coffee when your alarm goes off in the morning.
Basically, if there is something that is in any way controlled by electricity, the Arduino can interface with it in some manner. And even if it is not controlled by electricity, you can probably still use things which are (like motors and electromagnets), to interface with it.
The possibilities of the Arduino are almost limitless. As such, there is no way that one single tutorial can cover everything you might ever need to know. That said, I've done my best to give a basic overview of the fundamental skills and knowledge that you need to get your Arduino up and running. If nothing more, this should function as a springboard into further experimentation and learning.

Signing UpStep 1: Different types of Arduinos
There are a number of different types of Arduinos to choose from. This is a brief overview of some of the more common types of Arduino boards you may encounter. For a full listing of currently support Arduino boards, check out the Arduino hardware page.
Arduino Uno
The most common version of Arduino is the Arduino Uno. This board is what most people are talking about when they refer to an Arduino. In the next step, there is a more complete rundown of its features.
Arduino NG, Diecimila, and the Duemilanove (Legacy Versions)
Legacy versions of the Arduino Uno product line consist of the NG, Diecimila, and the Duemilanove. The important thing to note about legacy boards is that they lack particular feature of the Arduino Uno. Some key differences:
Arduino Mega 2560
The Mega is the second most commonly encountered version of the Arduino family. The Arduino Mega is like the Arduino Uno's beefier older brother. It boasts 256 KB of memory (8 times more than the Uno). It also had 54 input and output pins, 16 of which are analog pins, and 14 of which can do PWM. However, all of the added functionality comes at the cost of a slightly larger circuit board. It may make your project more powerful, but it will also make your project larger. Check out the official Arduino Mega 2560 page for more details.
Arduino Mega ADK
This specialized version of the Arduino is basically an Arduino Mega that has been specifically designed for interfacing with Android smartphones.
Arduino LilyPad
The LilyPad was designed for wearable and e-textile applications. It is intended to be sewn to fabric and connected to other sewable components using conductive thread. This board requires the use of a special FTDI-USB TTL serial programming cable. For more information, the Arduino LilyPad page is a decent starting point.

Legacy versions of the Arduino Uno product line consist of the NG, Diecimila, and the Duemilanove. The important thing to note about legacy boards is that they lack particular feature of the Arduino Uno. Some key differences:
- The Diecimila and NG use an ATMEGA168 chips (as opposed to the more powerful ATMEGA328),
- Both the Diecimila and NG have a jumper next to the USB port and require manual selection of either USB or battery power.
- The Arduino NG requires that you hold the rest button on the board for a few seconds prior to uploading a program.

I have a project that needs to contrlol relays to switch on/of 12volts.
Can Arduino capable of doing multi-switching (9 or 12 volts) around 6 to 10 switches?
I don't often open my account, would it be better to give me a reply on my mail?
at ronald_av@yahoo.com....Thank you very much.
I did select the Uno as my board. I reset it, I unplugged and replugged.
I still cannot get the serial port to allow me to make a choice.
Suggestions?
An Arduino is an open-source microcontroller development board. In plain English, you can use the Arduino to read sensors and control things like motors and lights.

A microcontroller is a computer chip, which is like a mini computer that controls things.
You attach microcontrollers (and other components) to PCB boards.
-What would be the best starter project for arduino?
-Do you recommend any particular books or ibles on this subject?
-Does a computer have to have USB 2.0 ports to operate an arduino?
(Mine only has USB 1.0 ports.)
if anybody has any other advice, please leave a comment below.
I recommend this one ;-)
...but you should try searching the site for some of the Arduino guides and eBooks. Those are pretty good. Also, arduino.cc has a ton of useful information. It just takes a little digging through.
What do you ultimately want to make with an Arduino? Once I have a sense of that, I can probably recommend some intro projects that might help you.
The people who won last year had a human sized hamster wheel that printed dot matrix words. People in the crowd were told to text it and it would print the texts.
It was awesome! :):):):):)!!
I had a n idea for a door that had a key fob so that I could remotely unlock the door to my room. Or build a system that would open up my closet doors when I pushed a button. : )
There are bunch of projects on Instructables for electronic door locks. You should search the site for those.
i am not able to understand why there is a 16Mhz crystal(SPK 16.000) on arduino(uno) board.
please help me out..
thank you....
my arduino works lights up the green light but when i upload code into it at the minute it says
"arvdude :verification error,first mismatch at byte 0x00000xc != 0x62
arvdude : verification error ; content mismatch"
i new to arduino and i just bought it 2 days ago
do you have some idea on what's going on

BTW: Didnt you forgot one popular Arduino?
The Arduino Nano http://arduino.cc/en/Main/ArduinoBoardNano
I often use it (Or a cheaper chinese replica) for the movement of the finished project off to the cheaper and final resting place...
You have been posting a lot of very helpful Instructables.
Thanks for this one and the many others.
Just scroll down with the scrollbar on the right of the textbox to see the rest of the content.
