[Simon Monk] got frustrated with bad ADC performance when tinkering with an ESP32 board, and decided to put three of the nowadays-iconic boards to the test – a classic ESP32 devboard, a Pi Pico with ...

The LinarADC library is designed to handle Analog-to-Digital Converter (ADC) operations on the ESP32 microcontroller. It supports raw and calibrated ADC readings, linearization via Look-Up Tables ...

This project is a smart assistant system capable of interacting via voice commands, monitoring ambient gas levels, and sending real-time notifications. The system consists of two main components: ...

Abstract: Low-cost electronic circuits for Internet-of-Things (IoT) applications are based on system-on-chips (SoCs) with wireless connectivity. Among them, the ESP32 is a well-known microcontroller ...

ESP32 microcontrollers, known for their versatility in IoT and smart home projects, also support digital audio via their I2S interface. In the first part of this series, we explore an audio-focused ...

The analog input of an Espressif ESP32 doesn't seem very reactive in the very first part of its allowed range, with a lack of response, and a non-linearity in the whole range, consequently. The aim of ...

The first step to reducing the energy consumption of your home is figuring out how much you actually use in the first place. After all, you need a baseline to compare against when you start making ...
