Sound10: This lesson will let you make use of the built-in sound with the EV3 robot. You will again use the if/elseif statements to tell the button what sound you want to make. As a bonus at the end after you press the escape key it will play all of the built-in sound again for you to hear. You will also learn how to display a integer variable on the screen. We are setting the volume to 50 (50%), 0 is off and 100 is the loudest.
