Scaffolding: NIME Music Box

               

This is a music box that plays "Mary Had a Little Lamb", creates a precautionary noise, and has a light

that can dim. There is an open front component that houses the precision servo and a back component

that houses all the electrical parts and wires. Within the back component, there is a Circuit Playground

Express(CPE) and a breadboard that controls and commands the entire box. Connected to the CPE is

the breadboard which houses a 1k resistor that connects to a white LED with a blue potentiometer that

is off to the side. The LED can be seen through a square hole on the top of the back component of the

box. When the potentiometer is turned left and right, it causes the white LED to dim and brighten. A

flathead screwdriver goes through the top of the back of the box and connects to the potentiometer for

the user to move more easily. A servo motor sits in the front open compartment, has a small piece of

wood screwed to its top and is also connected through the breadboard, and is controlled by the CPE.

A button is connected to said servo and when pressed, the servo and its wood piece spin back and

forth 180 degrees to create a precautionary noise. A small plastic rod also goes through the top of the

back component of the box for the user to push more easily. Finally, a speaker on the CPE can play a

short melody with the flip of a switch that is also found on the CPE. Another plastic rod goes through

the top of the back component of the box for the user to move the switch more easily. How could one

decorate this box to look more appealing?
