The TCS230 lowers colour light using an 8 x 8 array of photodiodes. When using a current frequency converter, the measured values of the photodiodes are converted into a square wave at a frequency directly proportional to the light intensity. Finally, we can use the Arduino board to read the square wave output and get the results for the colour.\n\n--\nOur eBay Store\n\nPlease note: This item has a longer lead time for dispatch then normal as it's a non-stocked item that is ordered in, please see the estimated delivery date by eBay.
