1. Project Description
The author is using IP-based door bell such as 2N Helios IP or Mobotix product. However, he has been experiencing discomfort since IP compatible sound module which enables people to hear the door bell sound does not vary. As a result, he made IP-based sound module which can sound using Arduino and Ethernet Shield.
The sound module that author made operates as web server and is implemented to ring upon receiving HTTP client request. One great feature for this sound module is that it uses Ethernet Shield including function of PoE (Power over Ethernet). If it is included the function of PoE, we can implement to operate the module and provide power through Ethernet cable without the separate power supply to the module. This is big advantage to simplify the connection of the device.
2. Parts
- Arduino Ethernet Rev3 WITH PoE (A000074) (or similar / successor), preferably with PoE
- USB 2 Serial Converter (USB Mini) (A000059) (for simple connection to PC for code upload)
- Small speaker, e.g. from an old PC
- Some other accessories like Mini USB cable, RJ45 LAN cable, some short wires
3. Steps and Source Code
