Development of Arduino-based logic gate training kit

Abstract

In this work, we develop a compact, robust, and portable Arduino-based logic gate training kit. It was designed for an electronic engineering undergraduate university course in order to learn a fundamental concept of logic gates operation regarding to six logic gates; AND, NAND, OR, NOR, XOR, and XNOR. An ATmega 2560 Arduino board was used to develop the training kit. It consists of two 3.7V batteries as a power supply, 2-input or 3-input selectors, and input pin connectors to connect the desired logic input. Therefore, the training kit can be used to explore the output of the 2-input or 3-input basic logic functions. The output of each logic function can be detected by the LED light (Green = high output, Orange = low output). Moreover, students can directly observe the output of the logic gate through the LED when they select the desired input logic 1 or 0. A size of the logic gate training kit is 19 × 16.5 cm which can be used easily in the typical classroom. Students are asked to predict the basic logic gates operation on the activity sheet before doing the experiment with the kit. After that students have to explain he operation of the basic logic gates. This provides the active learning environment to the students.
