-  WriteSingleField
-  
-  Description: Writes a value to a channel on ThingSpeak every 20 seconds.
-  
-  Hardware: ESP8266 based boards
-  
-  !!! IMPORTANT - Modify the secrets.h file for this project with your network connection and ThingSpeak channel details. !!!
-  
-  Note:
-  - Requires ESP8266WiFi library and ESP8622 board add-on. See https://github.com/esp8266/Arduino for details.
-  - Select the target hardware from the Tools->Board menu
-  - This example is written for a network using WPA encryption. For WEP or WPA, change the WiFi.begin() call accordingly.
-  
-  ThingSpeak ( https://www.thingspeak.com ) is an analytic IoT platform service that allows you to aggregate, visualize, and 
-  analyze live data streams in the cloud. Visit https://www.thingspeak.com to sign up for a free account and create a channel.  
-  
-  Documentation for the ThingSpeak Communication Library for Arduino is in the README.md folder where the library was installed.
-  See https://www.mathworks.com/help/thingspeak/index.html for the full ThingSpeak documentation.
