Отправка данных датчика arduino через Wi-Fi на сервер MySQL

WiFi.h предназначен для Arduino WiFi shield. Используйте библиотеку WiFiNINA для MKR1010

Так что я не совсем понимаю почему, но я начал с нуля, и теперь это работает. Я поместил новый код ниже на случай, если это поможет кому-то в моей ситуации.

  Repeating Wifi Web Client

  This sketch connects to a a web server and makes a request
  using a WiFi equipped Arduino board.
