Can Arduino Uno write to SD card?
Introducing the SD Card module The Arduino can create a file in an SD card to write and save data using the SD library. There are different models from different suppliers, but they all work in a similar way, using the SPI communication protocol.
How do I save Arduino data to a file?
You can use Arduino serial monitor and copy the data to save in a text file. Besides, you can use a SD card module as a datalogger and save the data both in a. txt and excel file. Also, you can use PLX-DAQ software to save the data in excel file.
Can you store files on Arduino?
If you want files, then you need a filesystem. The only simple to use and reliable things on an Arduino that have a filesystem are SD cards or USB memory sticks through the USB Host Shield.
Where does Arduino store data?
Flash memory (program space), is where the Arduino sketch is stored. SRAM (static random access memory) is where the sketch creates and manipulates variables when it runs. EEPROM is memory space that programmers can use to store long-term information.
How do I flash files to SD card?

Can you flash an SD card?
In order to flash an SD card with an operating system image, you need the file you’re going to flash and an SD card. An SD card isn’t always small, in fact you can find them in very large storage configurations. Make sure the SD card you have is as big as you need it to be.
