Hi. My school assigned me an arduino project, i know literally nothing about arduino. The students can choose anything to make, and i want to make a battery-powered bluetooth DAC/AMP from arduino. The workflow that i imagine is;
- My smartphone will connect to the device with bluetooth, and stream audio to it.
- The bluetooth receiver pass the info/codec/whatever to arduino
- Arduino pass the info to a Digital-To-Analog converter, making the output an analog audio
- Connect the output of the DAC to some amplifier.
so far i choosed these for the parts:
- Arduino Uno R3
- JDY-31Bluetooth Module
- MCP4725 Digital-To-Analog converter
- LM386 Amplifier
the main question is, will it work? why and/or how? I haven't purchased the parts so i need sort of checking from you guys. Any suggestion and/or advice would be nice for me. Cheers.
note : not sure to use the LM386 as it is mono and can drive only 8 ohms. I need this thing to drive Salnotes Zero which have >32 ohm on the specsheet.. not really sure what am i cooking to be completely honest..
