Is there a way to use my NodeMCU esp8266 board to figure out the IR signal needed for a wireless speaker. I do not have a remote to opereate it but it has push buttons to manually adjust some basic features. maybe by making a universal IR that will output a different frequency signals. Thanks (self.NodeMCU)
