Abstract
In this research, a cheap color distinction device has been developed. The developed color distinction device emits light of R → G → B in order at intervals of about 4sec with the high output LED.The reflected light is received by the phototransistor, and the voltage proportional to the amount of light as output. The microcontroller synchronizes with the luminescence trigger and takes in data of voltage of RGB. The data is converted from the analogue into digital, and displayed in the indicator. The color that is passing of can be judged by the displayed data. The performance of high output LED color distinction device was compared with the commercial color sensor. By the high output LED color distinction device,it is confirmed that the distinction of the color is easy.
