Description

I put FRSs,a green LED, and a Piezo Speaker inside a half opacity rubber sculpture. If I will push FRSs inside the sculpture, light and sound will be generated in it. In other wards, the sculpture is a pakage to make an Input/Output product.

Components

A rubber Sculpture, a green LED, FSRs, a Piezo Speaker, Arduino Board, Bread Board, wires,
