Доброго дня. Завдання цікаве. На перший погляд все зрозуміло. Вам потрібне тільки програмування чи розробка коробки куди це все розмістити?

если что, ws2812 пятивольтовый, на вашей схеме не взлетит.
И продолжительность работы системы от акб (U макс. 4.2в) через 1117 тоже будет не длительной. При падении на акб < 4в стабилизатор уже с трудом будет выдавать 3.3в.

Ну как-бы тут любой может оставлять сообщения, если что.
А чтобы по делу, то надо понимать что из себя представляет полная система. По одной только схеме не понятно что она должна делать.
