/*
Here's a code snippet to toggle the onboard LED of the Arduino GIGA R1 WiFi using a webserver. This code creates a simple webpage that has a button to turn on and off the LED.

When you upload this code to your Arduino GIGA R1 WiFi board and connect it to a Wi-Fi network, you should be able to access the webpage at the board's IP address. Simply click the "ON" or "OFF" button to toggle the LED on
