Communication over RS485 with Arduino
Required skills: Arduino, Electronics, Microcontroller
Looking for someone to program arduino.
Two arduino Mega shall communicate over RS485 and have a 50-200 meter of cat5 cable between them.
Arduino #1 will have several switches and potentiometers to control relays on Arduino #2 and have a display that will show depth and temperature from sensors on arduino #2.
Arduino #2 will receive signals from Arduino #1 and have at least 2 servo and 15 relays. Will also have a temperature sensor and pressure sensor that will be send back to Arduino #1 and to be showned on the display.

- The application has to comply with the descriptions that we will provide to the winner.
- Installation of the application will also be required.
- Source code should be documented very well.
- Application should be compatible with the 32/64-bit editions of these operating systems: Windows 7, Vista, XP, 2000 and Windows 2008/2003/2000 Server.
Please shoot if you have any questions left.

each time the Map View is toggled, map can be gathered from cache.
- There should be a language file in case we want to change the application language and compile the final application with another language.
- If a location cannot be determined or Google Map communication cannot be handled, user friendly messages should be shown and retrying opportunity should be given to the user.
Please ask your questions if anything is missing or unclear..

Arduino audio project
essing may be able to help here? Ideally I'd like the sounds to play through a PC. Unfortunately have no experience with Processing and very little experience with Arduino. I have the required hardware (Arduino Uno .... and I'm going to buy an adaptor(?) so that I can use 8 photoresistors), but need someone to write the necessary code (and guide me through implementing it!).
Please feel free to ask if you need more information!

Arduino Doorlock
, after this the door must be closed by the motor running backwards for 3 seconds.
The motor is just a DC motor
To be able to make the motor run backwards i want you to use a H bridge
The code must be 1-2-3
I need you to comment so i can learn what is done where and how.
You need to provide a picture so i can see every wire, so i am able to put it togetter myself
And the rest is up to you :)

Wifly RN-XV + Arduino Datalogger Counter
Hi I am working on a project where I have an Arduino Uno sketch that is working as a datalogger using a SD card, ethernet that saves data and posts to the internet as webpage.
I have a working sketch but would like to transfer it work with the Roving Networks WiFly RN-XV.
Looking for someone who has experience with WiFly to integrate the RN-XV into my other sketch.
Must have experience with Arduino and Wifly modules.

to working with you on this. Let us know what we need to consider, suggestions about this project, and what aspects of this project will be hardest or not possible. All bid amounts will be considered.
Because the other guy disappeared, we are looking for reliability, and good communication. We will pay in full at project completion.
Thanks

Interface Android Tablet with Arduino
oid Tablet.
*Modify the USB interface on the Arduino Uno to look like a HID device.
Constraints:
*Can be implemented with any inexpensive ~$ 100 Android tablet.
*The arduino needs to be accessible from a user level android application.
*The arduino should be powered by the tablet.
*Any hardware modifications should be easily repeatable.

Voice Over Artist
I am looking for voice over artist with American accent for a project flash presentation.
Presentation will be similar to attached flash presentation, I am still not sure to my client will come with the script, so I am not sure for the length of the voice over, but I need fast turnaround, may be I need final files in 1-2 days, so you should be very fast to get the job done.
Please provide samples of your voice over files.
Best regards,
Sample development with Friendly ARM kit
ents and revice your bid ..
We are looking for developers who already have experience on this kit and have samples of the kit with them.
Pl. give details of your experience and projects of similar nature and your suggestions. experience on GPRS/3g modem on linux is preferable.
If you have some alternative kit of similar or better specification (and price) then u can propose it also.

On mouse over popup / alt window
oussillon.html
Just click on a member's name (linked).
It must be exactly the same. Appear on mouse over link (with a loading system if possible) and disappear when mouse not on the "pop up /alt" any more.
I have already tried few things but you have to click outside popup/alt in order to close it.
I will inform you about it in further communication.
Thank you.

Effective Communication
tanding which is built up through face-to-face conversation. Telephonic conversations are necessary but less effective, and written communication have many pitfalls for unwary. The FSM needs to use all the three forms with skill, which may not come naturally to him. Training in interviewing, charring meeting, effective speaking and effective writing is readily available. Even in the smallest organization; an investment in the branch of training is always soundly made.
3D Animation required - person interacting with PC and kiosk
r>
You will provide examples of previous 3D animation work.
This needs to be completed within the next 2 weeks.
Do not reply if you do not have example work.
I do not require Avatar 3D, just 3D wireframe compsite.
I need a quick turnaround on this, you should be able to understand written English, communication over email, skype.
Payment split over 3 payments, no payment until I can see progress, final payment on UAT
Thanks

Webhosting Communication Software
intigrate to a java applet programmed for mobile phone.
This must allow users to connect to the internet via GPRS or whatever means avalible, and transmit data such as photos, music, and various other files to the eFoundry server for quick access from the users PC or phone. Basically providing a huge virtual memory card, accessed via this 3rd party java applet that must be download from the main PC based site i need made. Hope to hear from you soon.

I am open to other ideas and suggestions, but this has been on-going for awhile now and it’s recently become urgent.
All sites use mySQL database on a Linux Dedicated Server.
I will not accept any generic bids.
Please don’t bid if you don’t have the time or resources to commit.

Android radio app not working on some phones
two more in the near future. One will be to add some features and functionality to the existing Android App and the other will be a port to iphone/ipad.
App can be viewed here: https://play.google.com/store/apps/details?id=com.radiolost
This is a repost of this project. Bidder was selected and made no progress and provided little communication over two weeks. I need this done asap by an experienced, responsive developer.
