  Connect_WiFi.ino
      
  Library for communicating with a MySQL or MariaDB Server
  
  Based on and modified from Dr. Charles A. Bell's MySQL_Connector_Arduino Library https://github.com/ChuckBell/MySQL_Connector_Arduino
  to support nRF52, SAMD21/SAMD51, SAM DUE, STM32F/L/H/G/WB/MP1, ESP8266, ESP32, etc. boards using W5x00, ENC28J60, LAM8742A Ethernet,
  WiFiNINA, ESP-AT, built-in ESP8266/ESP32 WiFi.

  The library provides simple and easy Client interface to MySQL or MariaDB Server.

  MySQL Connector/Arduino Example : connect

  This example demonstrates how to connect to a MySQL server from an
  Arduino using an Arduino-compatible Ethernet shield. Note that "compatible"
  means it must conform to the Ethernet class library or be a derivative
  with the same classes and methods.

  For more information and documentation, visit the wiki:
  https://github.com/ChuckBell/MySQL_Connector_Arduino/wiki.

  INSTRUCTIONS FOR USE

  1) Change the address of the server to the IP address of the MySQL server
  2) Change the user and password to a valid MySQL user and password
  3) Connect a USB cable to your Arduino
  4) Select the correct board and port
  5) Compile and upload the sketch to your Arduino
  6) Once uploaded, open Serial Monitor (use 115200 speed) and observe

  If you do not see messages indicating you have a connection, refer to the
  manual for troubleshooting tips. The most common issues are the server is
  not accessible from the network or the user name and password is incorrect.

  Note: The MAC address can be anything so long as it is unique on your network.
