We designed an interactive toy that teaches color theory to children through levers that represent the primary colors which can be combined to create more colors and the resultant is displayed. The theme is a science laboratory where the child is the protagonist, thus being a scientist. For its realization, the Arduino system was used, which is an open source electronic prototyping platform based on flexible and easy-to-use hardware and software. Thanks to the hardware extensions that Arduino has, the toy can give feedback to users between 5 and 10 years of age. This system is needed to control most of the planned functions that the toy will perform. It has interactive and intuitive interfaces with which the user can communicate with the system, being these activated with levers and horns.
