Schematics

Nano - ESP8266

Shows how the ESP8266 Wifi Module should be connected to the Arduino Nano, according to the code supplied

Code

ReadOneSignal.ino

Arduino
ReadOneSignal.ino

This example code that shows how to read a signal using the circusofthings.com API through its CircusWifiLib-2.0.0 library for Arduino.

This code will temperature value beiing posted at at Circus.

A software serial port is used, so the onboard serial port is used to monitor the process. You have 3 degrees for monitor: DEBUG_NO,DEBUG_YES and DEBUG_DEEP.

There are no 3rd part libraries to use, beside SoftwareSerial.
