I have a 5.1 home theater(old one), I would like to transform it into a audio streaming system. I have a Arduino UNO and HC-05 Bluetooth Module, and I don't know how to install it in my home theater(if it does). solution please...
I don't think this will be feasible. There are two main issues:
1. I don't think there's a sensible way to get the HC-05 module to work with A2DP. It's great for a simple serial connection, but Bluetooth-enabled media devices generally won't connect to it if they're looking for audio streaming systems (as far as I know).
2. The Uno probably isn't powerful enough. Even if you could get the audio data into it, I don't think it will be able to decode the information to an analog audio signal in real-time.
Something like a Raspberry Pi with a suitable Bluetooth module might be a better choice for this.
