Hey There! I'm really new to the Arduino thing. Sorry for my english, I'm from germany.
I have an older car and no chance to upgrade the radio inside of it. I used a shitty bluetooth to FM transmitter but it's just cheap and the audio quality is also not the best.
I want to solder a arduino with power from my Car Output and connect my phone via Bluetooth (5.0?) To it and send the fm signal to my radio.
How?? I have some arduinos here and I want to get creative, but i don't know what I need and how to do it.
Is there somebody who made a thing like this, or do you have a tutorial for me? Can't find the right things online… Maybe I'm just searching for the wrong things?
