Project Level: Intermediate (soldering, use of Arduino IDE)Additional Tools and Materials Required The Apollo Light is a light-activated music player designed to provide automatic ambiance to any room. The player comes in two shapes (square, Mickey) and can be wall mounted with screws or double-sided tape.  Mickey-shaped players can also be displayed on the provided stand print. Bill of materials, instructions, and source code are provided, as well as a guide intended for end users for including with gifts or sales. The settings are explained in the bill of materials / instructions document, but a key thing to note is that you can reverse the light activation so that music is played when the room is dark instead of when the room is lit.
