/* SECRET_ fields are in arduino_secrets.h included above
 * if using a WiFi board (Arduino MKR1000, MKR WiFi 1010, Nano 33 IoT, UNO
 * WiFi Rev 2 or ESP8266/32), create a WiFiConnectionHandler object by adding
 * Network Name (SECRET_SSID) and password (SECRET_PASS) in the arduino_secrets.h
 * file (or Secrets tab in Create Web Editor).
 *
 *    WiFiConnectionHandler conMan(SECRET_SSID, SECRET_PASS);
 *
 * If using a MKR GSM 1400 or other GSM boards supporting the same API you'll
 * need a GSMConnectionHandler object as follows
 *
 *    GSMConnectionHandler conMan(SECRET_PIN, SECRET_APN, SECRET_GSM_USER, SECRET_GSM_PASS);
 *
 * If using a MKR NB1500 you'll need a NBConnectionHandler object as follows
 *
 *    NBConnectionHandler conMan(SECRET_PIN);
