Hi everyone, I have a small problem which I can not solve.
I state that I have already scanned many pages of the forum and that's why I'm here.
My problem is this:
I have a .txt file saved in the SD card of my Arduino UNO, inside there are data of this kind:
ID NAME MONEY
1 Cristian 500.00
2 Jon 300.00
I would like to take these data and modify them, in particular the data type float.
I tried in every way but I can not get them, modify them and put them back in the same position.
The research I want to carry out and on the ID.
Thanks a lot to everyone in advance
