Abstract: This paper illustrates the application of the color detection technique using MATLAB algorithms, to control the state of the output pins of an Arduino (AT mega 328) and also to control the movements of an iROBOT CREATE [1]. This gives a very small example of implementing Bounding Box algorithm [2] and use of the simple color detection technique and other ‘REGIONPROPS’ [3][4] parameters we can control the outputs of an Arduino board [5]and also control an iROBOT CREATE.
