Description: A Micro-SD Card Module connected to a Seeeduino Xiao opens the data.txt file on the Micro-SD Card and then reads and outputs that data onto the Serial Monitor.
Notes: Open the Serial Monitor and set the Baud Rate to 9600 in order to see the incoming data as in the picture below.
Supplies:
1 – Breadboard 400 Points >> Link <<
1 – Seeeduino Xiao >> Link <<
1 – Micro-SD Card Module >> Link <<
Arduino Code:
#include <SPI.h>
#include <SD.h>
File myFile;
void setup() {
Serial.begin(9600);
while (!Serial) {
; // wait for serial port to connect. Needed for native USB port only
}
if (!SD.begin(3)) {
Serial.println("Initialization Failed!");
while (1);
}
myFile = SD.open("data.txt"); // open the file for reading
if (myFile) {
while (myFile.available()) {
Serial.write(myFile.read());
}
myFile.close();
} else {
Serial.println("error opening data.txt");
}
}
void loop() {
}
