Hi, already figured out and tested a temperature data logger for my steam canner/cooker. My set-up was contained in an enclosure and have to open it up everytime to pry out the SD card to transfer it to my PC for printing and filing.
Now, would there be a sketch to program the Arduino to copy the stored files (whole .txt files) to a USB drive. Or do I need another Arduino (that woukd be portable) to hook in to the MCU in the enclosure to retrieve and copy the files in the SD card inside the data logger?
