Introduction
Online (or called remote-controlled) experiments are recently emerging as another important exemplar of technology-enhanced learning. For this invention, an innovative method was formulated with successful pilot tests to apply low-cost and open-source hardware and software for rapidly and easily developing online experiments which are embedded with effective pedagogies for facilitating teachers’ and students’ effective teaching and learning of STEM subjects. Through the internet, students can readily set and control the Arduino-based platform for conducting or observing authentic experiments in any computing or mobile devices at anytime and anywhere by using a web browser without installing any bulky or proprietary plugins.

The inventor has won a gold medal award and a special prize in the 2018 International Invention Innovation Competition in Canada as held at Toronto. Besides, we have obtained a university Dean’s research fund to conduct the related educational research to evaluate students' learning effectiveness with various online experiments in Hong Kong and Mainland China.
