The TCS230 detects colored light using an 8 x 8 array of photodiodes. Using a current-to-frequency converter, the readings from the photodiodes are converted into a square wave with a frequency directly proportional to the light intensity. Finally, using the Arduino board, we can read the Square Wave output and get the results for the color...
