So what should i do to use interrupts? I was integrating this interrupt code with your MQTT ESP8266 example and code was like this:
/*** Adafruit MQTT Library ESP8266 Example
Must use ESP8266 Arduino from: https://github.com/esp8266/Arduino
Works great with Adafruit's Huzzah ESP board & Feather ----> https://www.adafruit.com/product/2471 ----> https://www.adafruit.com/products/2821
Adafruit invests time and resources providing this open source code, please support Adafruit and open-source hardware by purchasing products from Adafruit!
