FIRST VERSION
Measure the robot speed in standard units (m/s) at different motor power (0...255).
Students program the robot to follow the black line. The robot is set at the beginning of the black line. The robot is started when the button is pressed and released. It is also the countdown time. Once you reach the goal, that is, when the robot invades the white, the robot should stop and display the passage time on the display.
