Have you ever been into a boring elevator ? with no sound and level indicator lights ? because I’ve been and i can tell you its not a pleasant environment to be in. Those elevators are sometime rebuild or renewed but the level indicator lights and some kind of sound system are not installed because of the high price tag, and possible need of rewiring. This project comes with a solution, and an easy to implement one.
It features a voice message system which inform you about the current level and optional about the next level. It needs no connection to the elevators system, its powered by batteries so you just need to stick it somewhere inside the elevator. If i would to build this system i would also include an FM radio, because most modern elevators include this features and i think its neat.
