//PURPOSE OF SCRIPT
//Create webpage
//Count number of presses and presses per minute for button connected to pin D2.
//Output this to web page

//Hardware is Wemos D1 Mini


// Include libraries 
#include <WiFi.h>
#include <WebServer.h>

// Set up the ESP32 webserver

// Set up a variable to count the number of button presses

// Set up the pins
#define BUTTON_PIN D2

// Create a function to handle the button press

  pressesPerMin++; // Increment the presses per minute
}

// Setup the ESP32
