IRJET - Frequency Spectrum Analyser through OLED Display using Arduino Controller
0 likes6 views
This document describes a project to create a frequency spectrum analyzer using an Arduino controller, microphone, and OLED display. An Arduino Uno microcontroller samples audio from a microphone and performs a fast Fourier transform to analyze the frequency content. It then displays the results as bars on an OLED screen, allowing the frequency spectrum to be visualized. The goal is to build a small, low-power spectrum analyzer for general audio frequency analysis using inexpensive, portable components.

Abstract -Spectrum Analyzer is an analog input reader
display on OLED,it performing FFT analysis, and displaying
frequency bin bars. For apply a Fourier Transform, we are
using fix FFT library. A fast Fourier transform (FFT)
algorithm numerates the discrete Fourier transform (DFT)
of a sequence. Its converts a signal from its original domain
(often time or space) to a representation in the frequency
domain and vice versa to an audio signal. The signal is
acquired through a microphone and is viewed in the
frequency domain on an OLED screen.
Key Words: Arduino, OLED (Organic Light Emitting
Diode), Microphone.
1. INTRODUCTION
At the forefront of this advancement are handheld
devices that are converting into numerating platforms.
This device smaller in size and lower power
consumption of such devices offers noticeable
advantages over any conventional measuring device
giving us opportunities to make use of them in the field
of measuring instruments.
An OLED stands for Organic Light Emitting Diode.
It is a light emitting device, film of organic compound
acts as the light emissive electro luminescent layer and it
mainly response to an electric current.
This paper mainly focusses on Arduino Uno
microcontroller device, it based on the Atmega328. It has
total 14 digital input/output pins. It has 6 analog inputs,
a 16 MHz ceramic resonator, a USB connection, a power
jack, an ICSP header, and a reset button.
A microphone is an electronic device; it works
that translates sound vibrations in the air into electronic
signals. This signal converted from an analog signal to a
digital signal.
2. LITERATURE OVERVIEW OF FREQUENCY SPECTRUM
ANALYSER THROUGH OLED DISPLAY USING ARDUINO
CONTROLLER
There are two types of conventional analyser
depending on their principle of working: First method is
Super heterodyne based and Second method is Direct
window based. First method is Super heterodyne based
on wide frequency range of operation over increased
system complexity, cost and size[1]. Second method
Direct window based on simple in design but it limits the
frequency range of operation[2]. Any signal measuring
instrument can be divided into either Analog or Digital
domain.
Analog instruments depend on greater accuracy
but increased cost and components size limiting its use
in specialized laboratories. Digital instruments signal
using advanced digital signal processing. It increased
processing powers and contraindicate a window based
digital domain spectrum analyser.
In this paper we are proposed a Spectrum
analyser for general purpose spectrum analysis of audio
frequency by using microphone. Some spectrum
analysers have integrated functions like modulation
decoding and radio frequency signal generation[4].
Modern spectrum analysers use digital techniques to
combine and reduce the hardware.

supply, power source is automatically selected. External
power can come from AC to DC adapter or battery. The
adapter connected plugging by 2.1mm center positive plug

communicating with computer[5].
In this research paper the (organic light emitting
diode) OLED display is use for displaying the output from
input.

voice by using microphone and then analysing the voice
and displaying on OLED display in the form of spectrum.
