This report discusses the development of an interactive e-learning environment for learners to understand more about Bipolar Junction Transistors (BJT) in Integrated Circuits (ICs). This project showcases the implementation of hardware components and software so that effective learning of the topic can be achieved electronically, and at the desired pace of the learner. The design of the environment is centred around the three areas of interacting, visualizing and reinforcing. With interactivity as a focus area, the project integrates both hardware and software together via a website that is complemented with hardware to simulate a laboratory environment. The website is designed to prompt learners to take charge of their learning journey. This is done by making the website visual, interactive, and inclusive of tools that support independent learning. For example, laboratory sessions, which are an integral component of engineering learning, include detailed guides to build the confidence of learners in working with BJTs in a laboratory setting. Hardware components are provided to complement these sessions for learners to gain a holistic understanding of the content. AWS Amplify was used to host, test, and deploy the frontend of this website. Learning content on the site was created using a combination of PowerPoint and Apple’s iMovie. Frontend development was done on Visual Studio Code in HTML, CSS and JavaScript. Using PixelPulse2 software and the ADALM1000 hardware module, the hardware is integrated with software as the circuit can be controlled via the learner’s personal computer. Learners will be provided with a hardware kit, with instructions on how to integrate it with their online learning to understand the topics being taught in a hands-on manner. For learners who do not have access to hardware, an online circuit simulator built on Falstad.com serves as a substitute, enabling learners to build, modify, and test circuits. The relevant circuits have been prepared and embedded on the website for learners to interact with. They can also modify the circuits for deeper learning.
