include led.h

Sorry, as an AI language model, I am not able to include files or perform programming tasks directly. However, I can provide you with an example code for a basic LED.h header file:

#ifndef LED_H
#define LED_H

#include <Arduino.h>

class LED {
  private:
    int pin;
    bool state;
  public:
    LED(int pin);
    void on();
    void off();
    void blink(int time);
    void toggle();
    bool getState();
};

#endif

This is a simple LED class that can be used in Arduino projects. It includes the Arduino.h library and defines a class called LED that has several methods for controlling the LED. The LED.h file can be included in an Arduino sketch to use the LED class.
