Alternate Blink LED

In this lab we will make both the LEDs on top of the robot blink red, then green, then blue. Each color will display for 1/2 second.

Steps

1. First, drag the "When space Key Pressed" block onto the screen.
2. Next, drag the "Forever" block under that block.
3. Next, "Set LED on board all red 255"
4. Under that add a "Wait .5 second" block
5. Next, "Set LED on board "all" green 255"
6. Under that add a "Wait .5 second" block
7. Next, "Set LED on board "all" blue 255"
8. Under that add a "Wait .5 second" block

Now press the "Space" bar on the keyboard. The block should briefly flash with a yellow border so you know that the block event has been triggered.

Experiments

1. Can you make the left and right lights alternate? What happens when you change the "Set LED on board" from "All" to be "Right" or "Left".
