//! Basic single-servo control example.
//!
//! Wiring:
//! - Servo signal -> GPIO10
//! - Servo power -> 5V (do not use 3.3V for typical hobby servos)
//! - Servo ground -> GND (shared with ESP32 GND)
//! - If using a separate 5V supply, connect supply GND to ESP32 GND (common ground required)
//! - Do not power a servo directly from a GPIO pin
//! - Common red/brown/yellow wiring:
//! red -> 5V, brown -> GND, yellow -> signal (GPIO10)
