Ejemplo
String myString = "Welcome to ArduinoGetStarted.com!\n";
void setup() {
Serial.begin(9600); // opens serial port, sets data rate to 9600 bps
int wlen = Serial.availableForWrite();
// prints the received data
Serial.print("TX buffer size: ");
Serial.println(wlen);
}
void loop() {
// check if Tx buffer is enough to write the string
if (Serial.availableForWrite() > myString.length()) {
// prints the string
Serial.print(myString);
delay(1000);
}
}
- The result on Serial Monitor:
8
Serial.println("Hello World!");
