Frequency Modulation (FM) broadcasting is a Very High Frequency (VHF) broadcasting technology. It was used to provide high quality sound broadcasts over radio. The Raspberry Pi is a credit card sized, single-board, system-on-chip computer. As such the Raspberry Pi has on-board hardware that is used to generate clock signals on the General Purpose Input/Output (GPIO) pins to output FM signal.
My proposal is that we will achieve a solution that results in having a FM Transmitter composed solely of the Raspberry Pi, an optional but recommended passive antenna, as well as source code written in the C programming language.
