MW transmitter using Arduino nano Circuit Diagram MW frequency  :-   Medium wave is the part of the medium frequency radio band used mainly for AM radio broadcasting. The spectrum provides about 120 channels with limited sound quality. During daytime, only local stations can be received.

FM Transmitter using Raspbarry PI model 3 B What is respbarry pi : - The  Raspberry Pi  is a low cost, credit-card sized computer that plugs into a computer monitor or TV, and uses a standard keyboard and mouse. It is a capable little device that enables people of all ages to explore computing, and to learn how to program in languages like Scratch and Python. Hardware requirement :- you can use raspberry Pi zeroW, raspberry Pi 2, raspberry Pi model 3b, raspberry Pi model 3b Plus, raspberry Pi 4. FM RDS setup :- Frist you go to GitHub and search FM RDS search results selected FM-RDS than copy clone link than go to terminal type $ sudo git clone (paste link) than prass enter file download start complete download than go to file path type $ cd PiFmRds/src press enter than type  $ make clean press enter  $ make press enter than automatic create run file. Run you pi FM transmitter type $ sudo ./pi_fm_rds press enter Run pi FM transmitter default frequency 107MH
