I tried the suggestion from Gunner below is the error message after I uploaded the sketch
Arduino: 1.8.1 (Windows 10), Board: "Arduino Uno WiFi"
C:\Users\John\Documents\Arduino\sketch_mar25a\sketch_mar25a.ino:36:25: fatal error: ESP8266WiFi.h: No such file or directory
exit status 1
Error compiling for board Arduino Uno WiFi.
This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.
