I want to feed Audio input (music played in my phone or laptop) to Arduino using an AUX cable(3.5 mm).
I know that we need to offset and amplify the signals as the Arduino takes input from 0 to 5v and the signals are very small.
I really searched all over the internet but couldn't find any step by step or basic stuff.
Please help !!
P.S. - I am not very mature in the field of electronics.
