This set-up allows 2 students to collaborate on wiring up the logic circuits.



In Electronic Engineering Principles (ET1201), students are introduced to Logic Gates through circuit construction on a breadboard. Without prior knowledge, this module can be daunting for students as they cannot fully grasp the circuitry logic. LogEE Gate uses interactive guided instructions to superimpose relevant graphics and explain concepts of Logic Gates through Augmented Reality (AR). This provides greater clarity and visualization to students, laying the groundwork for a quick, yet in-depth understanding, of breadboard and IC components.


LogEE Gate is an Augmented Reality software that runs on a PC that aims to assist students new to the field of electronics to breadboard prototyping, which is a key component of their practical tests for ET1201, Electronic Engineering Principles. Users can choose from a variety of circuits from the textbook in this software, which will all be taught to the student through step-by-step instructions with 3D reproductions of the real world part superimposed onto the breadboard in the camera feed, giving students great clarity on what needs to be done on the breadboard and allowing them to get accustomed to the hardware more quickly.

The tutorials each include a schematic diagram of the circuit being wired, with the most immediately relevant parts of the circuit highlighted for students to understand what they are currently doing. Students are able to return to previous steps to check their wiring if necessary, and they can, additionally, click on the 3D models of the components to learn more about those components and their properties through a pop-up screen.

Important details are always brought to the user's attention through instructions or visual indication. IC chips will have their "first pin notch" glowing to make sure students pay attention to the way they are orientating their chip, for example, teaching them to look out for the small details in electronics that can make or break a circuit, ensuring that they do not make the same mistake in their exams, and even in their working lives.

A custom breadboard mount is also used to ensure that the breadboard will be positioned in a way that the schematic diagram and instructions never obstruct the view of the electronics on screen. The time taken for students to finish the circuit will also be recorded and displayed for them to gauge their performance, ensuring that they will have the speed and accuracy needed to complete the circuit in their examinations.

After the completion of a circuit, the truth table for that circuit will be provided for the students to confirm their circuit's functionality. Students will also be able to capture a screenshot of their work at the end if they wish to keep it for future reference.
