Help and Guidance in my project

[elec_noob_tech]

Hi, there!
I am currently working on my first project that includes an arduino uno board. I am building a bluetooth audio amplifier speaker that has a screen. I have little to no experience with arduino and my coding skills and knowledge are not so great because I am not consistent with it, so I am here seeking help and guidance also to learn.

Components that I am using
Arduino uno board
HC-05 bluetooth module( I read that this doesn't receive audio input. Recommend one that is compatible to work with arduino uno that receives audio)
IC audio amplifier LM386
5v voltage regulator
Push button switch
Recommend auxiliary port compatible to work with arduino uno
2.4" tft lcd shield
3 18650 battery cells

How the system should work
1 push button switch to toggle between BT/ aux mode( turn on/off).
Then receive audio input from whichever of sources and output it through the amplified speaker.
The display screen should out put " welcome" when the system is turned on and "Goodbye" when turned off. While the screen is on it should display battery level. When switching source (BT /aux) should display which source it switches to.

In this case I believe you have the cart before the horse. Post your design Schematic, not a frizzy thing showing what you are planning on building. Explain what you are trying to do with eich piece of hardware and does its specifications support your plans. Links for the various hardware items. The LM386 is a great IC, do you have the skills to design a circuit around it and build it, it is a minimum 4V part? What sound levels do you want? What is the auxiliary port for. What type of battery life are you expecting? What is the battery capacity? These are just a few of the questions I have as I do not know your skill set and or experience. I would suggest you work on one part at a time and get it to work the way you want it to then the next, etc until you have them all working then combine them.
