Arduino_uSDX_Pico_FFT - Main code for Ajan-5, runs at Raspberry Pi Pico, compiled with Arduino IDE (look "Arduino IDE setup and notes" below). PCB - Schematic and PCB Layout on Kicad format.

A 23 Hz sine wave is generated with Arduino (PWM + RC filter). The signal is sampled at different frequencies (12, 20, 26, 46, 92, and 120 Hz). MATLAB is used to plot time-domain signals and compute ...

If you’ve ever wanted to make your own VU meter but were scared off by the signal process you need to study this tutorial. The one drawback to the hardware choices made here is that there are only ...

Abstract: Voice controlled hardware applications are ruling the modern era. Most of the home appliances are expected to be automated through voice. This project illustrates an alter method of voice ...
