Design of IoT Based Real-Time Color Recognition and Mixing Machine

Many industries and research organizations aim to design a color mixing system to increase efficiency and productivity and minimize human efforts. This paper presents the design of a fully automated color recognition and regeneration of an object's color. Further, it is augmented with remote operation. The designed prototype has a facility for manual operation to generate the required color by selecting various color options locally. It has sensors which detect the color of an object and generates the same color. These operations are controlled remotely via Internet of Things (IoT), where object color is detected remotely, and the same color is generated locally. Further, to meet the real-time constraints and parallel execution, the FreeRTOS is employed in the prototype. The prototype is built using cost-effective Arduino-based hardware and tested with multiple colors sensing and generation methods. The results suggest that the prototype is suggestive and can be made as a fine product with minor enhancements.
