AUTOMATIC MUSICAL FOUNTAIN WITH AUDIO FREQUENCY ANALYSIS USING FFT ALGORITHM
This paper presents the construction of an automatic musical fountain system controlled by audio frequency analysis using FFT algotrithm. Audio signals are taken from various sources such as: MP3 Player, Cassette, Laptop, etc and these signals are first amplified and then transferred into a Microcontroller Unit (MCU) to be processed. This MCU changes Analog signals into Digital signals by Analog Digital Converter (ADC). This unit also uses Fast Fourier Transform (FFT) algorithm to give out a range of audio frequency, instead of using a complicated hardware. With this frequency band, turning on and off the valve and light systems will create the lighting and water spray effects which should go well along with showed music.
