I have to take an audio signal from a 3.5mm jack pinout, make it go through arduino and then send it to my smartphone(via bluetooth i think) and listen the audio on my phone. I'm new in this and i don't know where to start. I have an arduino uno. I dont know how to make arduino take the audio input ( wiring and code) and how to transmit signal via a bluetooth module. Deadline in 2 weeks pls help :(((((( Thank you!
