1. Lego MINDSTORMS EV3

2. Programming Basics You Need to Know
Loop
Switch-Statement

3. Loop: The Basic Structure
Loop condition
(when the loop will stop running)
Code that will be repeated

4. Loop: Examples The Block of code that will be repeated in the loop
Timer
Loop for 10 seconds
Move Tank Block
Move tank forward at power 30 for 2 seconds.

5. Turn at a power of 30 for 1 rotation of the wheels.
Loop: Examples
Move Steering Block
Turn at a power of 30 for 1 rotation of the wheels.
Do while the gyro sensor does not measure a change of 90 degrees or more in the angle

6. Loop will run a total of 6 times
Loop: Examples
Play Sound Block
Bark like a dog
Loop will run a total of 6 times

7. Switch-Statement: The Basic Structure
Condition statement
Code that runs when condition statement is true
Code that runs when condition statement is false

8. Switch-Statement: Examples
the robot will make a “cheering” sound
If the color sensor measures an ambient light intensity of greater than 15,
Else, the robot will make a “Boo” sound

9. Switch-Statement: Examples
the robot will make a “cheering” sound
If the Gyro Sensor senses the robot turning at a rate of 90 degrees per second or faster,
Else, the robot will make a “Boo” sound

10. Switch-Statement: Examples
the robot will say, “blue”
If the color sensor measures an ambient light intensity of greater than 15,
Else, the robot will say, “no blue”

11. Things You Will Be Working With:
Sensors
Motors
Color Sensor
Touch Sensor (2)
Ultrasonic Sensor
Gyro Sensor
Large Motors (2)
Medium Motor

12. Sensors: Color Sensor

13. Sensors: Color Sensor Color Mode Black Blue Green Yellow Red White
Brown
No Color

14. Sensors: Color Sensor Reflected Light Intensity Mode
Measures how intensity of light reflected back from an object
0 (very dark) (very light)

15. Sensors: Color Sensor Ambient Light Intensity Mode
Measures intensity of light coming from the environment around it
0 (very dark) (very light)

16. Sensors: Touch Sensor

17. Boolean Value (TRUE or FALSE, 1 or 0)
Sensors: Touch Sensor
Pressed
Released
Bumped
Boolean Value (TRUE or FALSE, 1 or 0)

18. Ultrasonic Sensor

19. The Ultrasonic Sensor can measure distances in
Centimeters or Inches
This part contains the value that the sensor read. It can be dragged to blocks in which you need that value.

20. Ultrasonic Sensor
Compare Distance

21. Gyro Sensor

22. Gyro Sensor
The Gyro Sensor can measure the change in direction the robot is facing from the last time the sensor was reset.

23. Gyro Sensor
It can measure the angle that the robot has turned and the rate at which the robot is turning.

24. Gyro Sensor
It can also compare angles and rates with values that you choose

25. Gyro Sensor
It can also be reset with one simple block of code.

26. Motors
Large Motor (2)
Medium Motor

27. Motors Large Motor (2) Medium Motor
Built-in Rotation Sensor with 1- degree resolution
Programmable
Used for the movement and steering of the robot
Large Motors can be controlled together or individually
Built-in Sensor with 1-degree resolution
Programmable
Lighter than Large Motor, responds more quickly
