I have been working on a project that was coded on a NodeMCU. The question I have is if I want to use a UNO with a “KNACRO ESP8266 ESP-12E UART WIFI Wireless Shield Dev Board for Arduino UNO R3” from amazon, what has to be changed? When I do this I get the fallowing errors.
c;\Documents\Arduino\libraries\Cayenne-MQTT-ESP8266-master\src/CayenneMQTTESP8266.h:21:25: fatal error: ESP8266WiFi.h: No such file or directory
exit status 1
Error compiling for board Arduino/Genuino Uno.
