That was exactly our the trouble we had. The color sensor read the black, white, and red, but would not read the green. The kids thought calibrating the sensor would help, but nothing they tried worked, until they replaced the sensor with another. As soon as they did that it worked fine. I don't know if each sensor has it's own sensitivity or if the one they had been using all season was just worn out. My son said he's going to take
the replaced one and try it again at home, just to see what happens. It's interesting that your team also experienced the same thing!
Amy, thanks for sharing. We found this too. Our EV3 color sensor wouldn’t read green. We realized it was too close to the table. I am curious what you learned
during the competition that helped.

Subject: [VADCFLL-L] Thank you!
I want to offer a huge thank you from The Ruling Robot Falcons to Karen Berger and all the organizers, judges, referees, and volunteers that helped put on the regional tournament in Newport
News yesterday. Our kids had such a fun time and I appreciate all the work that was put into it! I think the referees were cheering for all the kids as much as the coaches were! Thank you all!
I also want to add a note about real Gracious Professionalism that happened for our team yesterday. When we arrived at the school yesterday and our kids ran their robot on the practice boards, they discovered
that nothing on their robot worked. All their missions were dependent on the color sensor, which had was only randomly seeing certain colors. They tried everything they could think of to fix it, but then got the idea to see if the other teams that had EV3's
could help. So they went around the room asking other teams if they had any ideas or knew how to calibrate a color sensor (one of the things they thought perhaps was wrong). The other teams all stopped what they were doing to help our kids try to problem
solve and help think of what could be wrong. It was very apparent that these kids were not just there to win a tournament...but they really loved being there and wanted to help. This just made me love FIRST/FLL even more than I already did, and realize just
how great this organization is!
