sequence_simple.py

# examples/async/sequence_simple.py
#
# Demonstrates: running a sequence of moves using sequence() — no hardware needed
# API style: async for loop (sequence)
# Sync equivalent: examples/basic/sequence_simple.py
#
# sequence() steps through each move in the list in order, looping if requested.
# Each tuple is: (target_position, time_secs, steps, easing_name)
#
# CircuitPython note: asyncio.run(main()) works with adafruit_asyncio v3+.
# On older CircuitPython, use: asyncio.get_event_loop().run_until_complete(main())
