WriteMultipleFields

Description: Writes values to fields 1,2,3 and 4 in a single ThingSpeak update every 20 seconds.

Hardware: Arduino Ethernet

!!! IMPORTANT - Modify the secrets.h file for this project with your network connection and ThingSpeak channel details. !!!

Note:
- Requires the Ethernet library

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.
