Hi, I'm new to arduino programming, and I'm not sure what I've done wrong here. This is my code (I've made the error line bold): #include <ESP8266WiFi.h> #include <SPI.h> #include <WiFi.h> char ssid[] = "SKY195DA"; // your network SSID (name) char key[] = "WRCWYBBY"; // your network key int …

Error message: invalid conversion from 'int' to 'char*' [-fpermissive]
