Here is a small task for you: implement a program where you start the robot, it moves for about a second, detects the minimum and maximum values, stores them in an array and displays this array on the screen. So, not the whole array but actually the second and the third cell of the array. Again, just move, detect the minimum and maximum and display this minimum and maximum on the brick screen.
Courses and lessons with this Tutorial
This Tutorial is used in the following courses and lessons

FIRST LEGO League Competition. Constructing and Programming a Robot Base
This course if used by teams, mentors and students to structure the preparation for the Robotics Game of the FIRST LEGO League Robotics Competitions. One thing that is common each year at FLL is that experience matters a lot. Our goal with this course is to quickly bring new teams up to speed with experienced teams and to share some new tricks, patterns, constructions with the more experienced teams.

Advanced Light/Color Sensor Calibration
Would you like to resolve all the problems with the light/color sensors that you have? And to make all of them work in a predictable, stable way even when using more than one MINDSTORMS colour sensors.
When using Color sensors it is important to calibrate them depending on the light conditions in your venue. In this way, the calibrated sensor will show values between 0 and 100 independent of the light conditions. But using the default EV3 colour calibration available in the colour sensor block could lead to unpredicted problems that are difficult to track and resolved especially when used with multiple Color sensors. So in this series of tutorial we implement the calibration ourselves discussing the principles of colour sensor calibration.
