181  Using Arduino / Installation & Troubleshooting / Including Libraries From Custom Location Issue on: May 07, 2013, 05:23:21 pm
I am having a wierd issue.  I have a ton of libraries from helping members.  So many that the list in the "examples" is longer than my screen is tall. 

My idea was to organize similar libraries in one folder.  I have tried every way I know of to get a sketch to recognize where the library is.

#include <led\Blink.h>
#include "led\Blink.h"
#include "F:\Applications\Arduino\arduino-1.0.4\libraries\led\Blink.h"
#include <F:\Applications\Arduino\arduino-1.0.4\libraries\led\Blink.h>
#inlcude "../led/Blink.h"

And every iteration between those.  Even tried using the Documents folder with the same outcome. But I cannot get the IDE to recognize the libraries.

Simple_Blink.ino:15:23: warning: led\Blink.h: No such file or directory

With all that being said, the Examples list finds the new folder with the libraries in that folder.  I can load a sketch from the list, but it won't compile when verifying.

Arduino IDE 1.0.4
Win7 x64

Anybody got any ideas?

If you want the simplest, go with the Uno.  If size is a concern, go with the Nano.

Both can do what you want.

You might want to Google "line following arduino robot."  Tons of info the subject.

Do you have a schematic of your setup?

I just wonder, finally if I finished the soldering the circuit. Do I need to install any firmware (Like BIOS in PC) to set up?

It depends on your setup.  How will you program the '328? ICSP?

As I found in original eagle file of arduino mini, it includes a crystal with four pins(x2 16MHz), but the pads are under the crystal, so that it is very difficult to solering. As a result, my supervisor suggest me to change into another package, but recently i can only find one (package hc49s) in stock, but it has two pins. That means I am not able to connect the crystal into ground.

That would be a Crystal.  The original Pro Mini uses a Resonator.  If you are going use a Crystal, you will need 22pF caps on each leg connected to GND.

Will it effect my testing if I do not connect the crystal into GND ?

Yes, it won't work..

What do I need to change in my schematic?

Use the Value command and change it to 16Mhz.

Found an online generator.

Pretty sure that smilie isn't doing much good.

Post the code in code tags.  Modify post, highlight code, click the # button, and save.

Have you double checked the connections?

I don't see any broken traces, but your pic isn't that good.

You can purchase another atmega328p chip by itself with the bootloader already installed and see if it's just the chip.
189  Using Arduino / Installation & Troubleshooting / Re: Yet Another "Serial Port Already in Use" Problem on: May 07, 2013, 11:46:38 am
In my poking and prodding I discovered that port name I listed above was a bluetooth port set up by my computer to talk to a smartphone.

I've read several threads where disabling the Bluetooth driver from Device Manager fixed their issue.  More than likely a bug with some Bluetooth drivers.
190  Using Arduino / Installation & Troubleshooting / Re: Arduino not communicating with Sanguino board - probable Java problem on: May 07, 2013, 11:42:42 am
1.5.2 is only intended for the Due.

I don't think so.  Where did you get that from?  I have an Uno and a Mega and 1.5 works with them..

I downloaded it, will install, and sanguino to it, and test this evening.
Assuming this version gives the same problem - what else might cause this?

Thanks in advance,

There are some fixes stated here:

Yes you can use the hardware serial pins for the MAX485, but while it's connected, you can't upload or use the serial monitor. 
192  Using Arduino / Project Guidance / Re: SoftSerial on the Pro Mini on: May 07, 2013, 11:11:51 am
the 328 only has 1 hardware serial port.  But the 328 can also run software serial.
193  Using Arduino / General Electronics / Re: Simple 12 volt output on: May 07, 2013, 10:39:08 am
Anything's possible..  What you need is a MOSFET to switch the magnet.  Since, the Arduino doesn't like 12V running through it, you can use the Arduino to switch the MOSFET on and off to control the 12V magnet.

Now, we need to know how much current the electromagnet needs to get to 6kg of force.  Maybe post a link to it?
Next, we need the specs of the"computer charger like adapter."  Post a link if you have to.

Have you tried using the entire example sketch?

Did you read the comment you just deleted?  Looks important.. hint, hint..
