The objective of this work is to create a programmable logic controller (PLC) for use in the pneumatics bench of the mechanics laboratory of UFVJM. It was created from an ATmega328 microcontroller, 7805 voltage regulators to control the input signals, and relay modules to control the output signals. The PLC has an SD memory card reader to read and interpret a previously made program in a software. This software was created with the use of Processing®, specifically to program the PLC from a graphical language. The software features an intuitive interface with all the input and output symbols needed to create programming logic in the Ladder language. Thus, all the work allows a better understanding of how the electrical and microcontrolled operation of a PLC, created for teaching in the discipline of hydraulic and pneumatic systems, should be. It also envisions the possibility of optimizing the equipment to allow even its industrial application.
