Nick_Pyner:
??? You need to be a bit more specific.
As the comment above says that if we upload the dumpfile example, it can read the content of the text file from SD card and will send it to the serail Tx & Rx, but I wanted a Jpeg file or a text file to be transferred.
to Quote PAULS he said it is possible
PaulS:
Yes, it is, if the hardware is compatible.
Then you said
I don't believe you can transfer a file with Arduino
So should I give up here ? If yes, then can I go for rasberry pi or some other micro controller ?
Thabks for your reply
