DIY spectrum analyzer is an easy project for beginners

Spectrum analysis is a technique that allows someone to observe the amplitude of various frequency ranges within a signal. The most common use case is in the world of audio engineering, as it is useful for tuning audio output. It can, for example, show you that a particular audio signal has little amplitude in the […]

This ‘crazy’ spectrum analyzer visualizes tunes with four Arduinos and 504 LEDs

Spectrum analyzers are a great way to visualize music, and “TUENHIDIY” came up with an interesting take on this device using not one, but four Arduino Unos. Each board receives the same sound input via a 3.5mm audio jack, and separately processes it to break out the left and right channels, as well as upper and […]

Arduino Powered 2.4 GHz Spectrum Analyzer Lets You

Arduino forum user [Blibo] shares its 2.4 Ghz spectrum analyzer project on the forum. The project is based on the CYWM6935 board (wireless), an Atmega 328 and a Nokia 5110 LCD- I finished the (mostly) permanent version of my 2.4ghz spectrum analyzer, and soldered it up. I included 3 modes for scanning (fast, slow, and […]
