Set a method of an object as callback for a timer

[chess-levin]

Hi Marcello,
I have an object that should be able to call a method triggered by a timer. But nothing happens when I instantiate an object of my class and call run():

class LightShow {

private:

  SimpleTimer timer;

public:

  LightShow(SimpleTimer timer):
    timer(timer),
  {}

  void run() {
    timer.setInterval(3000, show);
  }

  static void show() {
    Serial.println("Triggered");
  }
};
