The block is located in the Events section. This means it serves as the starting point of the program, so no blocks can be placed before it.
By default, this block triggers the blocks that follow it when the sensor detects red. This means that the program will not start until the color sensor detects the specified color.
The first setting is the port, where you must select the port to which your sensor is connected. By default, this is port A.
The second setting allows you to change the color that activates the block. You can choose between 8 colors and a no-color option!

Lesson 1 - Color Sensor
Introduction
In this level, we will learn how to use a new sensor - the COLOR SENSOR! We will also explore various robotics competition disciplines, such as FLL, Line Following, and Sumo!
Have you heard of any of these competitions? Would you like to participate in any of them?
We will start with the namesake of this site - FLL. FLL stands for FIRST LEGO League. An FLL competition has four categories: Research Project, Core Values, Robot Design, and Robot Game.
We will focus on the Robot Game, which takes place on a special field, like the one in the picture. The field has multiple missions that the robot should accomplish to score points. The robot that scores the most points in 2 minutes and 30 seconds wins.
Every year, FLL has a new theme, which changes the entire Robot Game Field. Teams have a few months to prepare their robot before the actual competition begin.
