Normally this module comes with a potentiometer for adjustment of the colour intensity while this is not. With which microcontroller you are using the sensor? The same Arduino Uno, then it should work the same as in this tutorial. If you are using some other controller like ESP32, they have different results.

Sorry, but WHERE on a TCS34725 can you see a potentiometer?

yes it can be made by just getting the range of the sensor. And based on the range if conditions can be created. Make sure else condition is also implemented otherwise the situation will not return to normal.

sure, I can help.
It looks like the issue is with the voltage input, there is a potentiometer on the colour sensor rotating it. It will change the value of the sensors.

If I use your circuit and skecht I only get nubers between 3 and about 30 on the serial monitor.
Its in correct tendence but much too low numbers. If I place red I get red to 25-30 … but NEVER more.
I already tested several sensors… same problem.

can u maybe help me ?

We want that whenever the green color is detected, the door should open. And for the red color, the door must remain closed. If the color of paper doesn’t match the standard values of RGB, we can still note the range of RGB values and, upon those values, red-colored paper and green color paper can be differentiated. Hence the reliance on standard values is not a must. We can also read values with the sensor, note them down, and programme according to real-time samples.

hello im new to arduino and i don´t know how to write the above example it is exactly what i need for my project. i need the arduino to react to the switch of red to green. i thought it might work with an if statement for example if (red => green) {
do a function
}
can u maybe help me ?
