FIRST VERSION
- Students observe what value returns the line sensor when it sees "two white colours”, "two black colours”, "left black, right white” or "left white, right black”.
- Students observe the reaction time in the program where the robot goes on the black at the speed of 255 and when it enters the white it stops (firstly in the scratch mode and then in arduino mode)
- Students program the robot so that it runs along the black lines.
