Analog to Digital Signal Processing with Arduino based Spectrum Analyser
In our original project, we explain what makes up a Data Acquisition System (DAS), cover the fundamental theory of a DAS and how to use one, and how to design basic filters manually or using online tools.
We complete the project with an Arduino Uno driven spectrum analyser and VU meter builds.
