Boolean algebra is one of the main elements for the construction of a digital circuit, such that disciplines that approach the subject have absence of practical classes for many times the lack of resources. The Arduino platform can be an alternative to practical classes, because it is inexpensive and contains pins of digital input and output that is sufficient for the manipulation of Boolean algebra. With the use of this platform, it is possible to develop library of functions, through programming, that represent elements of the discipline of Digital Circuits, such as logic gates and flip-flops, giving the user the freedom to use these tools to elaborate what they need. With logic inputs and outputs represented by push-buttons and LEDs, respectively, it makes classes more dynamic. In this way it is possible to use the library developed for various applications such as combinational circuits, sequential, counters, shift registers, among others.
