In the constant search for efficient industrial processes to guarantee high reliability, its environment has frequently witnessed more robust controllers to deal better with complex processes. In this context, this work presents the design of a Fuzzy Controller, embedded in an Arduino Mega microcontroller. This project uses a Resistor-Capacitor circuit and a Direct Current motor to validate the fuzzy controller effectiveness and compare it with other control techniques: classical PID controller. In addition, it was considered the storage capacity of routines in the Arduino board, regarding the dynamic memory according to the increase of new membership functions and rules. The fuzzy controller was embedded, where satisfactory results were obtained when compared to a PID controller, taking non-intrusive performance indices as validation parameters.
