I wanted a library for performing FFT on ESP32 on Arduino and extract both the fundamental frequency and the amplitude at that frequency. The most popular library ...

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 ...

Bojan Jurca’s open-source Arduino sketch "Esp32_oscilloscope," transforms any ESP32 board to function as a web-based oscilloscope accessible over WiFi. While the Scoppy project demonstrated the ...

Bojan Jurca’s “Esp32_oscilloscope” is an open-source Arduino sketch that can transform an ESP32 board into a web-based oscilloscope that works over WiFi. We had also written about the Scoppy project ...

ESP32 is a versatile microcontroller and a great starting point for anyone venturing into the IoT realm, but its configuration and interfacing of sensors can be challenging for new users. Arduino ...

Unlike other ESP Development Boards, the ESP32-CAM has no USB connector to connect it to a computer. This might be confusing for beginners when they try to program this development board for the first ...

We just got our hands on some engineering pre-samples of the ESP32-C3 chip and modules, and there’s a lot to like about this chip. The question is what should you compare this to; is it more an ESP32 ...

Some of the newer Espressif Systems wireless SoCs such as the ESP32-H2 and ESP32-C6 support Zigbee through their built-in 802.15.4 radio. It’s been working since the release of the ESP-IDF 5.1 ...
