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.

1. Investigating the Effect of Light on the Rate of Carbon Dioxide Uptake in Plants
The main objectives of this online experiment are:
- to investigate the effect of the light intensity and colours on the carbon dioxide uptake in plants, and
- to compare the effect of lighting on plants with different colours.
2. Remote electrical circuit experiments - Serial and parallel connections
- This set of online experiments will investigate the electrical properties for the following types of electrical circuits:
- lamps put in serial or parallel connection;
- batteries put in serial or parallel connection.
3. Investigating the Characteristics of Rechargeable Batteries
- This set of online experiments will investigate the following three main categories of rechargeable batteries:
- Nickel-Cadmium (Ni-Cd) battery
- Nickel Metal-Hydride (Ni-MH) battery
- Lithium-Ion (Li-Ion) battery
4. Reflection and refraction of light
- This set of online experiments will allow learners to investigate:
- Law of Reflection;
- Snell's Law of Refraction; and
- Total Internal Reflection
5. Online Experiment for Investigating Landfill Gas Production
This online experiment is designed and developed to
(a) To monitor the changes (methane level, carbon dioxide level, pH) in the landfill gas production process over a long period of time by an Arduino remote control platform.(b) To help learners get an in-depth understanding of the landfill gas production by comparing the methane, carbon dioxide and pH levels for different inducers.
