Construction of a low-cost mobile embedded system for computer numerical control and educational purpose

Abstract

This article describes the construction of a low-cost, mobile, CNC (Computerized Numerical Command) mini machine, bringing as its objective the gain of experience in relation to machining knowledge, where the device executes a list of movements written in the programming language G. For the development of the project, the Arduino Nano embedded system, two CD / DVD players and two H bridges (L293D) were used. Afterward, the assembly, programming and results of the project in question are described.
