About This Example

This example lets you turn the built-in LED on and off.
Do not forget to enter your SECRET_SSID and SECRET_PASS.

Code

#include <ESP8266WiFi.h>

String commands = "{\"commands\":{\"on\":{\"title\":\"Turn on the LED\",\"summary\":\"Turns on the on-board LED\"},\"off\":{\"title\":\"Turn off the LED\",\"summary\":\"Turns off the on-board LED\"}}}";
String toastOn = "{\"toast\":\"Turned on the LED\"}";
String toastOff = "{\"toast\":\"Turned off the LED\"}";
