Tenim VEU/SO, Amb el sensor tenim l'entrada analogica, per exemple hi ha biblioteques com library processing, spech to text, machine learning, voice recognition després pasa a --------- L'arduino, amb el master slave, i després pasa a ---------- les sortides analogiques, Actuadors, entre ells: processing, text to speach que aquests produeixen la VEU/SO.
