You make great projects, thank You. Wish I had more time….. The project in the title made me wonder where does the SD library keep the data read from a .txt file on SD card? Is there a size limit for how big file it can open?
Thanks, Janne Numminen
I’m sorry, but I’m not really sure if I understood your first question. Do you want to know how you can read the data from the txt file and save it on a variable for example?
As per the file size, I don’t know if there is a limit.
I’m sorry that I can’t help much.
Maybe if you try to reformulate your first question, I can help you better.
