First, you need to prepare the hardware setup according to the scheme and upload the code to ESP32. Then, you need to run the Streamlit app and connect to the ESP32. The app will automatically connect ...

Every machine has its own way of communicating with its operator. Some send status emails, some illuminate, but most of them vibrate and make noise. If it hums happily, that’s usually a good sign, but ...

This guide will walk you through the steps required to set up a virtual environment using venv and run the real-time FFT visualization application. Ensure your Arduino is connected to the correct ...

These days, streaming services are a great way to listen to music or podcasts on your computer or on the go. However, they lack one feature of the MP3 players and streamers of old: visualizations!

This audio spectrum analyzer utilizes an ARM7 LPC2138 microcontroller to create an FFT algorithm while performing digital signal processing without the use of special DSP processor. This audio ...

With the ever-expanding adoption of wireless in embedded systems of all types, there’s no question that having spectrum analyzer capability in an oscilloscope is a time-savings convenience for ...

Abstract: This paper belongs to a set of efforts aimed to improve the education of engineering in electronic and telecommunications, based on virtual equipment. It stand on a previous work called ...

RF and EMI engineers spend a great deal of time looking and plots of frequency and amplitude. Depending on the application, you may need a traditional swept spectrum analyzer for continuous signals ...
