In the sketch, only one SD card can be open at the same time, SD.begin(53). Note that the SD cards need 3.3 Volt as VCC but they cab handle 5V on the logical pins (or at least the ones I used). SD number 2, CS pin is connected to 13 (or any other unused digital pin). SD number 1, CS (chip-select) pin is connected to 53 and Attached the 2 SD cards as per standard instructions except for 1 pin: Also want to be able to copy a file from one SD card to another. Vin: It is defined as the input voltage, which is applied to the Arduino Board when it is using an external power source.Wanted to write 2 SD cards from one Arduino (Mega or other) with the SD library.RX and TX: The successful flow of data is represented by the lighting of the TX and RX LED.3V3: The 3V3 pin works as the output regulated voltage of 3.3V. ![]()
