Step 13: Troubleshooting

1. The marker is loose and the hole is too big.
A. Put some tape arround the marker to make it fit. 
2. What else can I use as wheels?
A. There is a lot of stuff to use an example is tupperware tops or lids.
3. The servos wont move.
A. Make sure all the connections are not loose double check them.
A. Also make sure the 9V batterty is new this servos will drain all its power.
4. When connected to the power I have check all connections still servos wont move.
A. Double check that you upload the code to the Arduino, and when connected to the power you don't see servos move a little
     it means that there is no code running in the Arduino.
          When the power is connected if you dont see any light on the Arduino that means the battery does not have any power.

Any help needed let me know I will be glad to help all of you.

<p>can we use dc motors instead of parllax servos with same aurdino code..?</p>
<p>cheap cheap cheap arduino parts...</p><p>https://sites.google.com/site/arduinouk</p>
this is such a good idea! could try 4wd + rotating pen. keep up the good work!
<p>The code was from the arduino web site</p>
<p>Great, thanks!</p>
very interesting and amazing. Can't we develop this project with a 3D scanner. It means first scan the image and draw it. I think you have a idea. I am waiting from your response.God Bless and Grate day.
<p>umm!!! interesting I will try something like that</p>
where did you get the code from?
You are very right JoshuaZimmerman
Or you could just buy a really small 9V to 2.1mm plug connector. Simple and easy to use. <br> <br>http://www.browndoggadgets.com/store/batteries/9v-to-2-1mm-dc-jack/ <br> <br>You can also find connectors with built in switches and hard cases.
How do you go about plugging a nine volt into the arduino? Which ports do I use?
1. You need this connector for the battery look at the link for a clear picture <br>http://www.radioshack.com/product/index.jsp?productId=2062218 <br>2. And this picture will help you see the connector to provide power to the arduino. <br>3. And here is were you connect the 9V battery to the Arduino. <br>
