On this project I have build a simple control panel for my Denon AVR (AVR-X4100W).

Most of Denon A/V Receivers are network ready, so you can control them within a web interphase or an app. There is no official documentation for the HTTP API (there is an official [telnet api](http://assets.denon.com/documentmaster/master/avr2112ci_avr1912_protocol_v7.4.0.pdf)), but it is easy to get the calls with a tool like [Wireshark](https://www.wireshark.org/). I use these HTTP calls to remote control the Denon AVR with an Arduino and Ethernet shield. My arduino control panel can power ON/Off the Denon and control the volume with a rotary encoder.
