Arduino IDE vs PlatformIO for ESP32
Arduino IDE is still a valid starting point for beginners, but PlatformIO is usually the better and more modern choice for ESP32 projects because it scales better, organizes code more cleanly, and fits real project workflows more naturally.
ESP32 vs ESP8266
ESP32 and ESP8266 are both popular low-cost WiFi microcontrollers, but the ESP32 is usually the better choice when you need more performance, Bluetooth, or a more flexible hardware base.
What is a Microcontroller?
A microcontroller is a compact chip that combines a CPU, memory, and programmable I/O pins in one package, designed to run firmware and control hardware directly.
What is OpenGizmo?
OpenGizmo is an ESP32-focused site for practical open-source gadgets, build pages, and maker notes that explain how the devices actually work.
What is the ESP32?
The ESP32 is a low-cost microcontroller from Espressif that combines WiFi, Bluetooth, GPIO, and enough processing power to build practical connected devices.
