i am new to this forum please let me if something goes wrong.
I am trying to make a weather station using Arduino UNO, ESP8266-01 and openweathermap.org API. While using in the browser i am getting long data. Now i want display in my serial terminal. i am attaching my code please help. This code written to know what are the data present in the receiver.
Some variables or header files that i am not using but still in the code.
#include <SoftwareSerial.h>
