Useful code:

Add your sensor object with the rest of your robot objects:

Hardware map it!:

Add some code like this to your main loop to read the values on your sensor:

Try something like this to drive until your sensor sees a red line:

while( color.red() < 100){
    backLeft.setPower(.5);
    backRight.setPower(.5);
    frontLeft.setPower(.5);
    frontRight.setPower(.5);
}
backLeft.setPower(0);
backRight.setPower(0);
frontLeft.setPower(0);
frontRight.setPower(0);

*Note, this code is not intended to work right off the bat… this is just an idea of how you could use a color sensor to control your robot!*
