4. cable.

PIANO CAPACITIVO
tipos de pianos capacitivo

 vamos a trabajar sobre un piano capacitivo con un sensor capacitivo 

Piano Capacitivo 

Hola , somos Nerea y Sara de 4 de la eso , en este blog trataremos sobre tecnologia y nuestro piano capacitivo , y muchos mas inventos ,que vamos a crear en clase , espeeremos que os guste y nos deis ideas pàra poder crearlo de diversas formas.
