Colour Sensor (Grove 101020341) component

Based on the color sensor TCS34725FN with digital output I2C. Based on the 8*2 array of filtered photodiodes and 16-bits analog-to-digital converters, you can gain the color chromaticity of ambient light or the color of objects. Of the 16 photodiodes, 4 have red filters, 4 have green filters, 4 have blue filters and 4 have no filter(clear). With the synchronization input pin, external pulsed light source can provides precise synchronous conversion control.
