WEEK 9 FYP2

SET THRESHOLD

during this week, i am doing my research how to set threshold for black marker pen colour. In order to make the colour sensor work for the automatic whiteboard cleaner, the threshold for each colour must be set. To set the threshold, each colour must be tested by using TCS3200.  

    To complete this automatic whiteboard cleaner project, the sensor are going to detect the black colour since the black marker pen are commonly used by the teachers. To detect the black colour, the sensor need to recognize the black colour first by place the sensor at black surface. The sensor are place for a few second on the black surface to determine the threshold.
