Picture of Intro to Arduino
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.

sir. this arduino uno can transmit or send information to another computer?
So awesome
so helpful:-)

I bought a new Uno board, and it plugs in and lights up, but the serial port command is greyed out.

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?

The same thing happened to me, I had to reinstall the drivers. This helped

...exchange it for a new one?
i obtained a 2nd one and same issue. I have windows 7, and downloaded the latest software. i will check for an update.
you might need to manually update the drivers, thats what i had to do with my mega 2560

I've made a few of the Arduino projects myself. So far I have made a failed robot (at the time I did not know motors would overwork the voltage regulator), two LED matrices (hackduino), and an RBG mood light (also hackduino). This is a great tutorial, and I believe I read it when I was first on the website and got my first Arduino. Could you add more information on programming into this instructable or do you have (or know) another one on programming in the IDE?

Thanks,

Sam.

Wonderfull tutorial! It has enlightened me up pretty much. I'm pretty much familiar to arduino now, and pretty much confident about not blowing up my projects. Thank you very much!

Im looking forward to work some animatronics projects using arduino lillypads.
Was guessing if there's a way you can bring me some starying data about Arduino, just like this you're publishing here, in a pdf format, so I can study it offline.
earslan11 year ago
Thank you, this is very good :)
Liked Arduino and I would like to study them.
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.

The Uno R3 is most likely the "best" Arduino to use. It is probably the newest, cheapest and smartest to use for protoboarding (or what ever you need it to do). It has a Atmel328 and is quit common, mostly used by beginners to Arduino, all the way to Advanced electrical hobbyists. But really, most Arduino's can use a sketch meant for " only one type of Arduino"

I'm trying to make a robot arm to grab things and place it in different places. Which Arduino should I buy? As a beginner, I am having some trouble in figuring out which Arduino to use... Thank you!:)

Excellent guide to get up and going with arduino! Thanks a lot!
First I have to be clear,what is Arduino I see that name all over the Internet?
randofo (author)  elfarandulero2 years ago
From the first paragraph of my explanation of what an Arduino is:

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.
Since I don't know anything about microcontroller; I like Electronics I keep using the regular PCB for my projects;let the wizard one work with Arduino; I don't need Arduino at this point
Some people think of the entire Arduino board as a microcontroller, but this is inaccurate. The Arduino board actually is a specially designed circuit board for programming and prototyping with Atmel microcontroller.. Then why not use a regular PCB board? I don't know a hell about microcontroller; I don't even know what is that and what is the use for microcontroller????/
randofo (author)  elfarandulero2 years ago
Because a PCB board is a fiberglass board with copper on it. It does not do anything.

A microcontroller is a computer chip, which is like a mini computer that controls things.

You attach microcontrollers (and other components) to PCB boards.
Hey Randofo!! I had a few questions about beginning in arduino.
-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.
randofo (author)  jackjackboom2 years ago
I think USB 1.0 should be fine.

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.
Also, is an led cube a beginner, intermediate, or advanced project?
randofo (author)  jackjackboom2 years ago
An led cube is probably a beginner to intermediate project. I would start small with a 3 x 3 x 3 LED cube. It may not seem like much, but that is 27 LEDs to solder together, which will take a bit of work.
I have the cube soldered together!! However I still need the resistors, transistors, and perfboard. Good luck at Red Bull Creation!!!
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! :):):):):)!!
randofo (author)  jackjackboom2 years ago
Good luck with the cube. We did our best on the challenge. Now it is up to the internet to vote for us. I guess we will see how it goes.
I finished it!! it works really well! Never fear with the voting. you've got everybody on Instructables supporting you guys!!
