Light Sketch
Created on 29 Oct 2018
A toy for children that lets them draw with light which can have child development applications.
In order to develop children’s motor and problem-solving skills in a fun way we intend to use Arduino as a platform. This can have applications in child developmental skills such as the ability to quantify the amount and method in which children draw.
