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. https://elecena.pl/product/28347986/whadda-wpse325-tcs3200-colour-sensor-module-arduino-compatible 2025-04-12 https://elecena.pl/product/28347986/whadda-wpse325-tcs3200-colour-sensor-module-arduino-compatible 2025-08-17
