This paper describes the development of a light polarization experimental apparatus for a remote laboratory. The apparatus had been developed by controlling the analyzer rotation using a stepper motor controlled via the Arduino. Device control and data acquisition applications were developed with LabVIEW which provides remote control panel facilities and web publishing tools. With the developed apparatus, light polarization experiments about Malus's law in physics teaching can be carried out remotely via the web. The results of the remote experiment show a good agreement with the theoretical predictions. It is concluded that the apparatus for remote laboratories is suitable for use in online experiment-based physics teaching.
