Web Interface to remote control a Denon AVR with an ESP8266 and a infrared led or the Room to Room connection.
There are 4 ways to remote control older Denon AVR's (in my case Denon AVR 2308):
Upload the INO file to the ESP8266.
You can get the IP address of the ESP8266 from the serial output or from your router. I configured the router to always give the ESP8266 the same IP.
You can test the IR led by looking at it with any phone camera, or by replacing the IR led with a normal led. It should blink when you use the web interface.
Currently only the basic functions implemented, but other codes can easly be read with a IR receiver diode, see for example here: https://github.com/crankyoldgit/IRremoteESP8266/wiki#ir-receiving.
