Audio spectrum analyser for a large LED screen. Contribute to bnegreve/arduino_spectrum_analyser development by creating an account on GitHub.

Upload the code to ESP32 using Arduino, or any other method you prefer. Pay attention on the problems with the analogRead function described in the documentation. Use the sketch in sketch_sample_rate ...

A fully fledged spectrum analyzer on a basic Arduino board? It is possible when the software is tailored to the available processing power. A standard Arduino can be turned into an AC line (‘mains’) ...

However, their spectrum analysis abilities are lacking. While these scopes do have a Fast Fourier Transform (FFT) function, it’s limited and nearly useless for RF.

This proposal addresses with a specific topic in radio frequency. Plenty of analysis is performed in the frequency domain due to limits for time analysis. In order to understand this phenomenon the ...

As it was mentioned our goal is boost the learning process, using IT infrastructure along with electronic prototypes, besides encourage students to use their pace in laboratory activities. The work ...

Although a spectrum analyzer exhibits better dynamic range and less distortion, the digital oscilloscope FFT provides a cost-effective, space-saving alternative.

First-person-view (FPV) flying, by adding a camera, video transmitter, and video goggles to the meat on the ground, is one of the best ways to experience remote-controlled flight. For just a few hu… ...

The spectrum analyzer uses a fixed number of 1024 samples for each FFT acquisition. That fixed size, combined with an FFT-overlapping process and a FFT rate of 146,484 FFT/s, results in a gap-free ...
