Hi
I also used a color sensor based on TCS230 (ZX-Color http://olimex.cl/website_MCI/static/documents/Datasheet_ZX-Color.pdf), but is very different. So, while typical sensor has 7 pins, ZX-Color has only 3 pins (one for 5v, one for ground and one for output signal). The output must be conected to analog input pin in Arduino UNO. I couldn't find any information about how to obtain the separates R, G, B signals. All information, codes and libraries on internet is based on 7 pins sensor.
Please, any help will be aprecciated
