Tweet Using Thingspeak API
Posted: Sun May 17, 2015 11:50 pmI had found code for updating a twitter feed using NodeMCU and LUA to program the ESP8266 directly by github user ok1cdj, but didn't find much help with doing this in the Arduino IDE which supports programming the
ESP8266 directly. This code when flashed to the ESP8266 allows it to connect to an access point and update a twitter feed with the account linked at thingspeak.com. Maybe this will be useful for somebody, so I will just leave it here.
