int x;

String datos;
void setup() {
Serial.begin(9600);
}
void loop() {
x = random(0, 10);
y = random(10, 100);
z = random(100,1000);
datos = (String) x + "," + (String) y + "," + (String) z;
Serial.println("Números aleatorios:");
Serial.println("Random numbers:");
Serial.println(datos);
delay(800);
}
Note that it only shows up when a list of 3 items arrives. Not shown:
