Automatic Color Generation Using AVR Microcontroller

ABSTRACT Today automation plays an important vital role in small scale industries & also in very large industries are becoming more popular due to their flexibility, easily interfacing and provides a cost effective solution to user. Therefore the stage has come in which, the efforts are being made in making the computer program in systems more and more user friendly to get connect or interfaced with our property for automation reason. The main theme of project is based on the simple working principle of how a Television generates various colored images on a single screen. There are three primary colors that are red, green and blue. Using proportionate percentage of these basic primary colors as concentrates can make any color or its shade. Here in our system we use a feedback to control the adding of concentrates. We monitor the output color after proper mixing of concentrates. Our system uses a database for various proportionate percentage of the basic primary color related to desired output color. Initially the theoretically calculated percentage of concentrates is added to water. Then depending on the output of color sensor, the processor will control the valves so as to add the concentrates to get the practical desired color.
