Example code and description how to use ESP32 low noise amplifier (LNA), including Arduino library and ESP-IDF component

This code catches I2C communication by running on an ESP32 board that are connected to I2C BUS lines as a passive listener.

The ESP32 LVGL Watchfaces project enables the display of pre-built binary watchfaces on ESP32 microcontrollers using LVGL. Through a Kotlin script, it converts binary watchface files into LVGL-compatible code, simplifying the process.

This repository contains code and diagram for ESPNOW RC Car using esp32

Arduino code for ESP32 based DIY quadcopter drones, providing autonomous flight via artificial neural network.

Camera QR-Code Recoginize use esp32 with ov2640

This repository contains code and diagram for using PS4Controller with esp32

The code shows how to play music using ESP32-S3 and MAX98357 in IDF v5.0.

Minimal code for a 'bare metal' ESP32 program which does not use ESP-IDF. Really just a learning exercise because the ESP-IDF is Apache-licensed and quite good; I just had trouble finding lower-level information about the chip.
