A New Color-Based Instrument Model For Basic Music Learning

The development of applied hardware technology supports efforts on the education and creativity of users and has made microcontrollers a popular device among education practitioners and researchers. The focus of this article is learning for children in the introduction of activities in color-based creativity. A model design of a color-based musical learning instrument device, composed of 2 main elements. The TCS3200 color sensor and arduino microcontroller, used to convert system inputs in the form of unique pieces of color paper arranged on a plastic tape, will be the instrument's modeling keywords. The size of the color paper piece is the same width as the plastic tape, which is 5 centimeters, while the dimensions of length are 5 centimeters to represent the beat of the tone every second. The process begins with color selection of tone characters, color recognition and color classification. Meanwhile, the design of the system algorithm, has the ability to detect colors, determine the tone according to the choice of color categories, and adjust the stability of the speed of the DC motor 60 revolution per minutes. The final test results of the system successfully proved the color detection process of sensor input and tone audio selection according to the classification of specified categories while proving that the system is able to work properly.
