1  Using Arduino / Installation & Troubleshooting / Re: Tools & Help menu lag in IDE install on: December 21, 2012, 01:23:03 pm
wow that was easy. Worked like a charm. What we be the cause of the conflict between the bluetooth and the Arduino IDE?
2  Using Arduino / Installation & Troubleshooting / Tools & Help menu lag in IDE install on: December 21, 2012, 01:01:13 pm
I am helping a student set up his dell windows 7 laptop with the Arduino IDE. We have install Arduino 1.0.1 and 1.0.3 several times. The IDE boots up, slowly and the tools and help drop down menus will not open.  With out the tools menu we have been unable to upload in sketches to the arduino.

Any ideas?
3  Using Arduino / Installation & Troubleshooting / Re: Arduino "compatible software driver" error during driver update on: December 20, 2012, 11:28:04 am
I definitely have the Leonardo .inf file. as for online search, our school district locks down our computers so online driver searches don't work. I am going to try and re-image the computers and see if that works.
4  Using Arduino / Installation & Troubleshooting / Re: This problem for people about "Not in sync" error. Any updates? on: December 14, 2012, 04:54:17 pm
It could have been the batch that i had. For me it makes a lot more sense to help students with their projects on stable platforms then running around troubleshooting and and burning boot loaders. When you are teaching you to minimize any thing that will frustrate students. Plus i would rather pay for the Arduino brand boards, they developed the boards and supporting them means more advances and cooler things.
5  Using Arduino / Installation & Troubleshooting / Re: This problem for people about "Not in sync" error. Any updates? on: December 14, 2012, 01:20:47 pm
I teach with Arduino and I see a couple hundred boards in a year. I had purchased a batch from a local supplier that were darker blue then the regular Arduino boards and that have a red power LED. Since this purchase i have had some students by the same boards off of Amazon. The boards all say made in Italy but are not official arduino boards, they resemble a lot of the made in china knock off stuff . Any way every single one of them has giving me the "Not in sync" error at some point in their lives. I can change the 328 but eventually, "Not in sync" re appears. Most these boards have hit the trash in my class room because they got to frustrating to trouble shoot with students. 

Check the board for a red LED, it could be a knock off board sold to you as the real thing.
6  Using Arduino / Installation & Troubleshooting / Arduino "compatible software driver" error during driver update on: December 12, 2012, 12:02:09 pm
I recently had a windows 7 upgrade with my engineering lab and have had to re-install all of my Arduino drivers. 25 computers were not a problem, but 5, all using Leonardo have given me a new error. (see attached file) All 30 computers are the same, with the same image.

I have tried using the Leonardo driver from the 1.03 and 1.02 release and nether one works. I have tried to use Uno rev3 on those computers as well and the same error appears. Has any one seen this before and found a solution for it?
7  Using Arduino / Networking, Protocols, and Devices / Need an android app that works with a JY_MCU bluetooth module on: October 21, 2012, 06:40:55 pm
I have just purchased several jy-mcu blue-tooth module to use with arduino uno's. I would like to be able to use the module to control a small robot. I have a sketch that allows me to read the information coming in to the arduino and that end of things seems to be fine. What I need is an Android or Apple app that sends clear enough data that I can write a sketch to use it. I have tried AndroidComander,  Blueterminal, cellbot and blue bots, all of these did not send useable information. I would like something that sends a simple value back to the arduino. Such as 1 for forward, 2 for back wards and so on. If at all possible something that can send usable accelerometer data when the phone is tilted.
Thank you.

I have been testing this shield with the Leonardo for a month now. i have never lost the COM port while using it. The UNO still has the problem and it boggles my mind, but with the Leonardo working i have a solution.

thanks,

I am going to place the order tonight

that sounds like what i need. we are going to use them with android devices to drive some simple robots and control LED's
11  Using Arduino / Networking, Protocols, and Devices / e-bay Blue tooth module on: September 09, 2012, 11:14:09 am
I want to know if any one has purchased blue tooth modulus from e-bay. I Have had good luck with distance sensors but i am unsure about blue tooth. If you have had a good or bad experiences with a seller please advise. I need to purchase 10 of them to use for a lab set for high-school students.

I don't under quite under stand the slave hoist options as well. if any one has insight into that it would be greatly appreciated.

the shield is not using the serial pins. It plugs into 5 volts (l293d only), ground, and pins 6,9,10,11. On the shields with the error problem the error occurs when the shield is plugged in to the arduino and without the secondary power hooked up. Holding down reset at the start of the upload does not seem to do anything, but i will test that on some of the other boards during the class today.

The issue is defiantly not impatient students, i try to do it with their boards and i get the same error. My money is on Wandersons conclusion of electrical noise. The question is what can be done to stop the electrical noise? and what pins would most likely cause the com port in use problem if they were exposed to the electrical noise?

we are using windows xp

The problem occurs only with the motor shield on. when it is off and the Arduino is unpluged and pluged back in every thing is back to normal, untill the motor shield goes back on. I think it has to be some sort of feed back issue.
