Where are we from?

Arenagiochi s.r.l. From 1956 is specialized in entertainment products (flipper, juke box, videogames…) „ Evolution to videogame (e.g., slotmachines) and necessity to design inside the company the products „ Creation of technical group of engineers and graphics „

Company Skills „ „ „ „


Hardware design Software development Test Capability to obtain Certification for Stringent Government Standards (protocol implementation and security remote comunication and control) ISO9001:2008 quality certificate

Why not? „

Idea to applied our skills to other embedded application


AED creation: ¾ New

experiences ¾ Increment know how ¾ Increment capability of team working
