Reading a push button properly: pull-up, debounce and interrupts
How to wire a button to the ESP32 without headaches: internal pull-up, why it bounces, software and hardware debounce, and interrupts done right.

Fundamentals
ESP32 fundamentals: variants, pinout, toolchain and best practices.
Getting started with ESP32: blink an LED
Set up your toolchain, understand the pinout and write your first ESP32 program by blinking an LED. With Arduino and with ESP-IDF.
ESP-IDF in depth: projects, tasks, logs and partitions
A practical guide to ESP-IDF: project layout, idf.py, menuconfig, FreeRTOS tasks, logs, OTA partitions and when it is worth it over Arduino.
Arduino core for ESP32 in depth: install it, understand it, stop fighting it
How the Arduino core for ESP32 really works: installation, setup and loop on FreeRTOS, millis vs delay, compatible libraries and the differences from classic Arduino.
Which framework should you use on the ESP32? Arduino, ESP-IDF, MicroPython or Rust
An honest comparison of ESP32 frameworks: Arduino, ESP-IDF, MicroPython, Rust and Lua. Which one to pick based on your experience, your project and your time.
ESP8266 vs ESP32: when the little one is (not) worth it
Real differences between the ESP8266 and the ESP32, what each costs, where the 8266 still makes sense, and why today the ESP32-C3 beats it almost every time.
