Blinking LED with ESP32
Control a GPIO pin to blink an LED — the "Hello World" of embedded systems and the foundation of every IoT project.
Interactive 3D hardware visualizations, animated workflow diagrams, and hands-on code demonstrations — not just documentation.
Each module walks you through an IoT concept visually — from theory to 3D hardware, from circuit connections to working code.
Understand what the concept is, why it matters, and where it's used in real IoT products before touching any code.
Watch the internal execution flow animate step by step — see exactly what happens inside the ESP32 when code runs.
Rotate, zoom, and click on a 3D circuit board. Inspect every connection, component, and GPIO pin interactively.
Every important line of Arduino/ESP32 code comes with a plain-English explanation of exactly what it does.
Control a GPIO pin to blink an LED — the "Hello World" of embedded systems and the foundation of every IoT project.
From microcontrollers to cloud connectivity — every layer of the IoT stack, visualized.
