AM means Amplitude Modulation.
FM means Frequency Modulation.
In either case, you need some hardware that can function as a modulator.
The Arduino cant, as theres nothing in it that can perform this function.


Always go for the simple best way to achieve your goal. I suggest you to build a simple stereo FM transmitter and connect it to the phone and transmit it. Use a low power FM transmitter, you can get very cheap single chip FM transmitter, which will works well with a small number of discrete components outside the IC.
