i have 1602 LCD Keypad Shield , TCS3200 color sensor ,ardunio uno board . i try many time but no result word color detection code. please anybody send me circuit diagram and code ??
Send us the wiring You used and the best code You have made.
Lots of diagrams and code examples at our favourite oracle.

Why didn't you read the forum sticky? Posting code using code tags prevents smileys from appearing in there.
You also forgot to give a clear description of what this code does, and how it is different from what you want it to do.
A quick look does show a major issue: in color() you take three readings, store the value in an int while that function returns an unsigned long. That's bound to be a problem if that pulse is longer than 32 ms.
...but before you wrote all that, you had a simple test sketch that simply reported colour values to the serial monitor, and didn't bother with the LCD.
That sketch presumably produced satisfactory results, so go back to that, and build it up, step by step.
i have these devices for color detection.. i want to color code showing on LCD key pad shield plz any one guide me with code and design
i dont understand witch pin of lcd on shield
