25.- Simulation of an arithmia.

Arduino sends a random level (90...100), with a random delay (400...1600)

void setup(){
  Serial.begin(9600);
}

void loop(){
      int nivel = random(90,100);
      int ritmo = random(400,1600);
      delay(ritmo);
      String mensaje = (String) nivel + "," + (String) ritmo;
      Serial.println(mensaje);
}

App Receives Text (98,977), gets the level (98) and draws it on a Canvas.

For a more realistic process, use the module AD8232
