ThingSpeak allows up to 8 fields for free account.
For this project, we used all 8 fields. (follow the pictures)
Copy CHANNEL ID and Write API Key (in API Keys) and paste it in mega/src/parts/thingspeakAPI/internet.cpp (shown in picture below)
you can update the WiFi part with SSID and Password. (ONLY WPA/WPA2 only)
