RANCANG BANGUN ALAT PENGIRIM DATA AUDIO KE SPEAKER AMPLIFIER MENGGUNAKAN SINYAL FREKUENSI MODULASI (FM)

This final report explains how to design a device that can send audio data to the speaker amplifier. In this tool uses frequency modulation module (FM) in order to transmit voice data wirelessly and use the relay circuit as a regulator on / off amplifier based on a command from the microcontroller. Input of the microcontroller is ADC value which is a state of the presence or absence of music that goes from the source of the music player. If the source of the music contained music player is running it will automatically relay will be turned ON the amplifier circuit and vice versa. In making this tool aims to minimize the electric power consumption is wasted when no music is being run. Keyword: Sending audio, frequency modulation, amplifie
