Step 10: Wire breadboard and sensor

Connect 5v to the positive column thingy in the breadboard. Connect GND to the negative thingy. Connect the yellow sensor thing to analog pin 2.
<p>muy bueno y facil de utilizar.</p>
very nice' but can we use a ultrasonic sensor in place of the SHARP sensor????????????
<p>can we use this module and normal male to female wires to connect it to the bread board?</p><p><a href="http://www.ebay.in/itm/Ultrasonic-Distance-Module-HC-SR04-Arduino-ARM-and-other-MCU-/141472357785?pt=IN_Toys_Games_School_Stuff&hash=item20f068dd99" rel="nofollow">http://www.ebay.in/itm/Ultrasonic-Distance-Module-HC-SR04-Arduino-ARM-and-other-MCU-/141472357785?pt=IN_Toys_Games_School_Stuff&amp;hash=item20f068dd99</a></p>

<p>I'm having trouble installing the library.</p><p>I downloaded the zip file and imported the library, but when I put it in the sketch it only shows the .h file and gives me the error message: <br><br>core.a(main.cpp.o): In function `main': <br>C:\Program Files (x86)\Arduino\hardware\arduino\cores\ard... undefined reference to `setup' <br>C:\Program Files (x86)\Arduino\hardware\arduino\cores\ard... undefined reference to `loop' <br><br>The four &quot;example&quot; files show up in the sketchbook, but each opens in a new window. They individually verify, but when copy/pasting them together I get error messages. <br><br>I can't seem to import the .cpp file at all, and when I try to drag and drop it I get the same error message.</p>
does arduino uno r3 work
hey <br>i also wannna do a similar stuff. i want to design a robot for surveillance where the robot will be fully autonomous and it wil move for point A to point B autonomously. <br>i want u to help me in designing the autonomous motion planning system to go form one given place to the other using sensors n stuff...i m stuck pls help <br> <br>i have bought the rover system from here just for making prototype of the actual system since i got it at a good price... <br>http://danuc.com/index.php?main_page=index&amp;cPath=6 <br>http://danuc.com/index.php?main_page=index&amp;cPath=4 <br>http://danuc.com/index.php?main_page=index&amp;cPath=1 <br>http://danuc.com/index.php?main_page=index&amp;cPath=7 <br>http://danuc.com/index.php?main_page=product_info&amp;cPath=8&amp;products_id=52 <br> <br>pls reply
my brother would approve of your username, he has the same problem with his name.
Very nice tutorial. Simple and to-the-point. Thanks!
Glad I could help!
Hello Guys! <br> <br>Could i use Motorshields from this Collection? <br> <br>http://www.amazon.de/s/ref=nb_sb_noss?url=search-alias%3Daps&amp;field-keywords=Arduino+Motor+Shield+R3 <br> <br> <br>?? I cannot buy the Motorshield R3 on Amazon.US, because i dont have VISA or a Mastercard.
Yes, you could.
add a bluetooth slave to this to make it even better! cheap remote control car your android phone!

The motor shield you are using has a relativly high current demand. One standard nine volt battery cannot supply that current. With my shield, I was needing power supplys with at leaste 800ma, and settled on using a 1600mah battery for all projects using that shield. Did the 9v battery actually drive the shield?
Yes, it works just fine for me.
Interesting. Your motors must not have a very large current consumption then.
Great tutorial, and just at the right time for me. My next project is to be a robot just like this. Thanks for the helping hand

(If you're going to glue your battery in place, best make sure it's rechargeable...?)
I didn't think that through very much, thanks for pointing that out. I think even if they were rechargeable, it would be difficult to recharge them while they're glued on. I suppose velcro, or some sort of holder would the best way to solve that problem.
You can get clips for the terminals, and clips for the actual battery - I'm guessing most folk will go that way. <br> <br>Since I have your attention, it would be nice to see a video of Carduino on the move...?
Video is soon to be posted.
