move_simple.py

# examples/async/move_simple.py
#
# Demonstrates: a simple move using move() — no hardware needed
# API style: async for loop (move)
# Sync equivalent: examples/basic/move_simple.py
#
# move() steps through every step of the move, yielding at each one.
# Awaiting each step lets other coroutines run — this is how concurrent
# actuators become possible.
#
# CircuitPython note: asyncio.run(main()) works with adafruit_asyncio v3+.
# On older CircuitPython, use: asyncio.get_event_loop().run_until_complete(main())
