"""
Basic analog output control example using icsneopy library.

Demonstrates how to configure and control analog outputs on supported devices.

Usage: python analog_out_basic.py <pin> <voltage> [--yes]

Arguments:
  pin: Pin number (1-3 for RAD Galaxy)
  voltage: Voltage level (0-5)
  --yes: Skip confirmation prompt
