I just got an arduino uno. I want to turn it into a bluetooth receiver for music from my phone. Could someone please tell me which shields I need. You don't need to tell me programming yet. Thanks
You want a Bluetooth module made for sending and receiving audio. Those BT modules can be found in various bluetooth headsets and other devices, but finding one online may be a little harder. Im not sure it there even is a shield yet for bluetooth audio or if there is even going to be one, but it doesn't hurt to look.
Ebay has some.
Edit. The URL didn't work like planned, but just search in eBay, Bluetooth audio module
