O objetivo deste projeto é detectar uma pessoa seja na base ou no topo da escada, a partir daí, acender um led após o outro com um pequeno delay para facilitar a visualização dos degraus, após todos os degraus estarem iluminados, cada led se apagará com um delay novamente entre eles. É um projeto simples mas com uma pegada de acessibilidade.
