Abstract: A light sensor works by reflecting a bright light onto the object and through IR it reflects the brightness of the colour which in turn is converted to a colour, based on its RGB values. This main aim of this paper is to compare results when detecting colours using the colour sensor (rev-31-1154) and the raspberry pi Camera v2. The colour sensor (rev-31-1154) has a built-in IR (optical) and its main feature is that it allows the user to return all the colour and status data in one read command, which makes the process faster and more accurate. The PICamera is a powerful tool which not only takes still and moving images but also has the capability to detect colour based on RGB filters. To be able to detect colours using the latter, openCV library will be installed and its functions will be called and modified using python. In order to detect the colours, the same experiment will be set up and tested using the colour sensor and the PI Camera module. To test this experiment various coloured cubes 3cms x 3cms x 3 cms will be placed in front of different coloured squares 5cms x 5cms. The result of this experiment is to identify the best option which yields the optimum results vis-à-vis accuracy and efficiency will be integrated into our robot and used for the tournament.
