sequence_simple.py

# examples/basic/sequence_simple.py
#
# Demonstrates: running a sequence of moves using sequence() — no hardware needed
# API style: call sequence() on every loop iteration
# Async equivalent: examples/async/sequence_simple.py
# Easing reference: https://philvanallen.com/easings_cheatsheet/
#
# sequence() steps through each move in the list in order, looping if requested.
# Each tuple is: (target_position, time_secs, steps, easing_name)
