“Its cool while working with digital circuits in frequency modulation, Gives you flexibility and more features with the custom PCB design.
Hello guys, today we are going to have a look on, How I made an Arduino based FM and then turn its circuit into a fully functional PCB. In this tutorial you will learn, basic FM working, Arduino code for this FM, range, speakers, antenna and amplifiers used in this circuit. This type of digital circuits has a very big importance over any analog based circuits. It will reduce the circuitry and tuning methods.
Features:
1) Based on digital method
2) Needs very less components
3) Stereo channel availability
4) Easy to tune
5) Onboard volume control
6) Large bandwidth (50MHz to 115MHz)
7) No coils, no variable capacitors
8) Low power consumption”
