Arduino SD card as File system and send images to Raspberry Pi

Recently, I have a project that I need to transfer images in the SD card of Arduino to Raspberry PI. I know that I need to transfer them bit by bit. But how? I really need some help. Thanks.

I know that I need to transfer them bit by bit.

Then, you don’t know squat. You need to transfer data one byte at a time. That is trivial, since the functions to read from a file on an SD card read a byte and the functions that transmit data, whether that it via Serial, i2C, or SPI send data a byte at a time.

I have already transmitted successfully. Thanks. BTW, just type error, I meant bit not bite :smiley:
