Step 5: Settings

Before you can start doing anything in the Arduino programmer, you must set the board-type and serial port.

To set the board, go to the following:

Tools --> Boards

Select the version of board that you are using. Since I have an Arduino Uno  plugged in, I obviously selected "Arduino Uno."

To set the serial port, go to the following:

Tools --> Serial Port

Select the serial port that looks like:

/dev/tty.usbmodem [random numbers]

<p>Thanks, very useful and informative. </p><p>I have however one reservation about many Arduino projects. Isn't it wasteful of resources to use an Arduino for instance just for watering a plant? </p>
Thanks, this is very useful
<p>Thanks for this Instructable. </p>
<p>Thanks for this Instructable. </p>
<p>Thanks for this Instructable. </p>
Learned how to use arduino. <br><br>now thevtime for make a arduino yourself
<p>I'm just getting started with Arduino and this Intro helped a lot. You made it simple and easy to understand. Thanks for writing it.</p>
<p>Hi, Your article was the mos comprehensive and easy to understand. </p><p>Can i have your permision to make video tutorial based on your article ? Please let me know</p><p>thnks</p>
<p>This article was the most comprehensive and easy-to-understand one I ever read, thanks!!</p>
<p>how can i code arduino uno for my project automatic alarm system connected to lcd 16x2 and rtc ds1302 controlled by arduino uno bluetooth?</p>
<p>I am new to arduino say me step to glow led and run motor </p><p>i have arduino uno R3 and arduino Mega 2560</p><p>also say simple project using LED, LDR, </p>
<p>Browse for a number of projects. You can do wonders with Arduino... Try them with interest. Definitely you will learn a lot.</p>
<p>Hi,</p><p>If you're looking for a tool to help you create the circuit schematics or code snippets, check this one:</p><p><a href="http://www.circuito.io/" rel="nofollow">www.circuito.io</a></p><p>It's free and fast</p>
<p>This is the best guide for beginners that I have come across. It will be a big help when I start creating my project. A former coworker bought me an Arduino UNO about 5 years ago and it was just sitting here collecting dust, I finally came up with a project to utilize it. I will be creating a ham radio repeater controller, which shouldn't be too hard to do for the basic controller but could get complex as I add more features to it.<br></p><p>I'll be doing this project in two stages.</p><p><br>First Stage Goals:</p><p>■ When the receiver squelch is triggered the arduino needs to trigger the transmitter to start transmitting (COR will go high or low, I need to check the radios to see if it goes high or low, when the radio receives a signal)<br>■ Route receive audio to transmitter <br>■ Every 10 minutes inject morse code audio into the transmit audio to satisfy FCC requirements<br><br>Second Stage Goals:<br>■ Add a couple second hang timer onto the end of each transmission (This will keep the transmitter keyed up for a couple seconds after the squelch signal is pulled low or high after it stops receiving a signal)<br>■ Add a courtesy tone at the end of each transmission<br>■ Add a time out timer (I might be able to do this on the radio but I prefer to try and do it on the Arduino)<br>■ Add DTMF decode functions to shut down the repeater (not sure if this will be doable)<br><br>For radios I will be using my set of Yaesu FT-7800r dual band radios, these radios have a 6 pin mini din connector on the back that will give me access to all the lines I will need.</p>
<p>Great info, thanks.</p>
<p>/port is not recognized by my laptop??</p><p>can i know what will be the reason??</p>
It might be because you don't have the right drivers for your laptop:)
<p>Thank you,found helpful............</p>
<p>how much small dc motors can I control with the arduino uno r3 I want the numper of motors that I can control with pwm and without pwm with on and off and direction</p>
THANK YOU! Really interesting and usefull.
<p>slt je suis terminale et mon projet un suiveur photovoltaique bi axiele mon probleme et le programme arduino pour 1 moteur pas &agrave; pas unipolaire tourne 9 h ( 7h &agrave; 16h) et puis retoure &agrave; l'etat initiale est attendre 14 h (16h &agrave; 7h ) et merciiiiii bcp </p>
<p>LOL: Step 12: You can think of this kind of like understanding grammar and punctuation. You can write an entire book without proper grammar and punctuation, but no one will be abler* to understand it, even if it is in English.</p><p>Great tutorial! Learned a lot.</p>
<p>I am considering building a collection of instructables on beginning Arduino.</p><p>Do I have your permission to include this instructable?</p>
Hi, I'm running Windows and I can't select the port for arduino uno. What could be wrong?
is arduino uno better than arduino mega
can I use arduino mega like arduino uno
<p>YES <br>ONLY DIFFERENCE IS THAT MEGA HAS MORE INPUT OUTPUT PINS</p>
<p>And more space than Uno ( 8x more space ) </p>
<p>GREAT INTRO FOR ARDUINO</p>
<p>Thanks! This is a great place to get started in the amazing world of Arduino. Bookmarked.</p>
Good. Guys you may visit this site to get more tutorials for free. http://electro.nitishdash.com
<p>great! like it</p>
sir. this arduino uno can transmit or send information to another computer?
So awesome
so helpful:-)
sir can me make a arduino at home????
<p>yes its possible...it will cost you around $8,here is the link </p><p>http://www.instructables.com/id/How-to-make-an-Arduino-from-scratch/?ALLSTEPS</p>
simply awesome
I bought a new Uno board, and it plugs in and lights up, but the serial port command is greyed out. <br> <br>I did select the Uno as my board. I reset it, I unplugged and replugged. <br> <br>I still cannot get the serial port to allow me to make a choice. <br> <br>Suggestions?
<p>The same thing happened to me, I had to reinstall the drivers. This helped</p><p>http://forum.arduino.cc/index.php?topic=104698.0</p>
...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
<p>Exactly what I was looking for. Thanks.</p>
<p>my arduino does not seem to be connecting to the program i selected arduino uno and the program wont let me select a serial port NEED HELP PLEASE!!!</p>
