Above is my code. I'm working on a shield bot for school and it needs to be able to pick up colored toy chickens. Whenever the colored chicken goes inside of my robot's grippers the Adafruit_TCS34725 color sensor activates. this bot is autonomous The bot stops itself from running into walls with a parallax sonar sensor. Whenever the color sensor activates, the sonar sensor goes crazy. I get readings that go from over 1000cm to 0cm back and fourth.
