Hello everyone, here's my project. I'd like to use Arduino as an SD card reader that upload photos on a web service, like Dropbox, over a Bluetooth or an USB connection to a smartphone. The user puts the SD card in the SD shield, then connects Arduino to its smartphone to choose files he wants to upload and selecting the right available options. I really don't care about performances of this system, that's just an experiment. It would be great to make kinda standard interface to navigate into an SD file system using a smartphone.
Anyone wanna tell something about it? Wanna help? Wanna tell me i'm a fool? Has anyone already done something like this? Is it as difficult as finding a girl in an italian engineering college?

Wrong again KE7!
The Arduino can easily talk to a mobile phone.  All the work is done.  Depends on the mobile phone:

That will be the easy part if you have the right phone.

The hard part will be interfacing to Dropbox since they don't have an Arduino library.
Choose an easier alternative.
Start with reading the SD card?

You have to read the next line after the one you quoted to find out.

Oh wait.  Why not just buy a mobile phone for $20 that has an SD slot?  Then you can do what you asked!

Can a Phone read "normal" SDcard? No, usually smartphones can only read microSD card, so here's why I'm trying to design this kind of device.
I was thinking about a person in vacation, in his hotel room, connected to the hotel WiFi network with his smartphone. He has taken a lot of photos and wants to upload them directly from his room, without using a laptop. He could connect this device to the smartphone, then browse the file system in the SD card of his camera, then select and upload the best photos and finally format the card to get more space for more photos or video.



Start with reading the SD card?



Yes that would be useful to create first a standard interface for "normal" SDcards file browsing over a smartphone. Then the interface could be used for other systems. The objective is to create this kinda standard interface for a mobile phone to browse external flash memories, then the applications would only depend on the smartphone's software. So you're right, maybe the card reader is the best thing to do first.

Any advice for the best mobile operating system to develop for? Would it be hard on iOS?
