I watched a video a few days ago where someone used a Bluetooth module soldered to an audio Jack + a speaker to play all his songs.
I want to use an old speaker who has a audio jack 3.5; then wire my bluetooth module to the audio jack using an AUX cable and finally pair my phone with the BT-Module to reproduce my songs.
I've been trying to do the same with my HC-06 bluetooth module, but I don't know how to wire it to the Audio Jack. I'm not sure if this is possible or it it's just a hoax! Please help me.
Attached is a picture of what I'm doing and a schematic on Proteus. Thanks in advance.
