Hello everyone, my name is Aaron I want to start a project but a need a little help getting started in the right direction. My project is to upgrade the steering wheel in my Toyota Corolla to a newer model featuring steering wheel controls. I want to control a JOYING Android 10.0 stereo using Bluetooth. My original idea was to solder the wires from the new wheel to a universal Bluetooth stereo controller. Now I am thinking of building the device myself with a microcontroller and think it would be a cool and educational project. Can you please give some pointers on what would be the best way to go about this. I am thinking that the ESP32 low energy Bluetooth functionality might work well as a battery saving controller? Thank you in advance for your time and consideration.
How much experience do you have?
I took circuits in college, I am working on getting a ham radio certs, I can solder, I have tinkered with linux code on my Chromebook but as far as using a microcontroller total noob 
Well, that's probably good enough to begin with. It would be a challenging first project, ideally you'd have a few "under your belt" before attempting this. But you could do it bit by bit, interface the wheel first, then the BT, etc. etc...it would help you get up to speed. I haven't looked at Bluetooth protocols beyond serial comms, so I'm not sure about the controller part. Is there not much on the web about this?
Udemy is having a new year sale of 80% off courses so I bought a course in Python programming language Bootcamp I'm a quarter of the way through it. I also got beginner and advanced courses in Arduino and raspberry pi. Go from there I guess.
