i have Arduino and an SD card which is working perfectly.
how can i create my own file ?
what i mean is, if i send "Test" through serial monitor
how can i convert "test" into test.txt and save it to SD??
any idea?
void receiveEvent(int howMany)
{
int i = 0;
while(Wire.available() > 0)
{
message[i] = Wire.read();
i++;
}
lcd.print(message);
myFile = SD.open(message, FILE_WRITE); //How can i convert the content of message to .txt to save in SD? please help.
myFile.close();
}
