First of all，I have implemented a project which store camera snapshot image into SD card. The project is show as below:
the parts list:
1 x Arduino UNO
1 x 2M_TTL_Camera
1 x SD Card Breakout Board
1 x SD card
Several jumper wires
then I wanna add a Bluetooth module(4.0 of course) and implement an app in iPhone（yes I am learning swift and know there are some Bluetooth frameworks in iOS development.) which can get the jpg in the SD cards.
So the question is:
1.Could the idea work?
2.Are there some similar projects which I can learn from?
3.Any problems I may meet and any suggestion?
I wil log my processing in this subject, thanks!
