This example shows a minimal Arduino sketch template for the Raspberry Pi Pico W, providing a starting point for C-based programs in the Wokwi simulator. The code initializes serial communication using the `Arduino.h` library’s `Serial.begin()` method, prints a greeting message with `Serial.println()`, and then enters an infinite `loop()` with a short `delay()`. It demonstrates the basic setup and loop structure required for microcontroller development, with a placeholder for adding sensor reading or actuator control logic.
