Your Arduino loop() Runs One Task. ESP-IDF Runs Ten — Here's How

Arduino's loop() is a superloop — one thread, sequential, blocking. The moment you need a sensor reading every 200ms, a UART log every second, and an LED blinking every 500ms simultaneously, it falls apart. The ESP32 already ships with FreeRTOS built in. ESP-IDF gives you full access to it. With xTaskCreate(), each concern becomes an independent task — its own stack, its own priority, its own schedule. The scheduler handles the rest. vTaskDelay() yields the CPU instead of burning it. Queues move data between tasks safely, with zero race conditions.
