(arduino) help to write / read a file and values on a (micro) sd card


I have some basic understanding / experience with arduino langage / (UNO) board to make some cool / useful devices.

I would like to learn how to save / load datas on a (micro) sd card.

I need your help to learn how to :

-check if sd card is present

-list all files on the sd card

-check if a file exists

-create a file

-delete a file

-open a file

-close a file

-write / read a byte in the file

-write / read a short in the file

-write / read a integer in the file

-write / read a float in the file

-write / read a string in the file

-fill an array with random (integer) values

-write the values of the array in the file

-read the values in the file and put them in an array

we will use a arduino UNO board, and we can use a (micro) sd card reader / writer like this one (or similar) :

Once it works as described, the work will be considered finished and i will release the milestone.

Your bid is only for this step, and we will discuss if we work together on another related step.

If you have any questions, don't hesitate to ask.

Thanks for your interest in this project,
