OK, now you know how to put data into a variable (Write) and how to get data from a variable (Read). You also know how to create additional variables. The last thing I want to cover in this chapter is how to use variables throughout your programs. Here s a bit of pseudo-code for SPOT: Me: SPOT, I want you to wait for me to press and release the Enter button (orange button) for 3 seconds. Me: If I press and release the button, display Pressed on the screen. Me: If I do not press and release the button, display Not Pressed on the screen. I ll first start off with a WAIT block configured to loop for 3 seconds (see Figure 18-11).

Figure 18-11. The WAIT block is configured to loop for 3 seconds. I ll next drop in an NXT BUTTONS SENSOR block and configure it to detect the press and release (Bumped) of the Enter button (see Figure 18-12).

Figure 18-12. The NXT BUTTONS SENSOR block will monitor the Enter button.
CHAPTER 18 TITLE = ANYTHING YOU LIKE
I created a new VARIABLE block called Pressed that holds a Logic value. I next drop a VARIABLE block after the NXT BUTTONS SENSOR block. I choose my new variable, Pressed, and in the Action section, I choose Write. I also drag a data wire out of the NXT BUTTONS SENSOR block s output data plug into the input data plug on the VARIABLE block (see Figure 18-13).
Figure 18-13. The variable Pressed will hold True or False. If the Enter button is pressed and released during the first 3 seconds, the NXT BUTTONS SENSOR block will detect the press and release and change the logic value to True. A value of True or False will continue to be written to the Pressed variable block until the 3 seconds expire. When the program starts, the initial value will be False, but it can change anytime to True if the Enter button is bumped. When the WAIT block ends (after 3 seconds), we need to display Pressed or Not Pressed on the LCD screen. To do this, we ll drop in another VARIABLE block. This time I m going to choose my Pressed variable again, but I m changing its Action section option to Read (see Figure 18-14).
Figure 18-14. The variable Pressed will be read from by a SWITCH block.
CHAPTER 18 TITLE = ANYTHING YOU LIKE
Now, I drop in a SWITCH block and configure it to read a Logic value (see Figure 18-15), and I ve turned off Flat view so the SWITCH block is visible in its tabbed format. I ve also dragged a data wire from the VARIABLE block to the SWITCH block that contains the value True or False.
Figure 18-15. The SWITCH block will read the Pressed variable s value. In the True tab, I place a DISPLAY block that clears the LCD screen and puts the word Pressed on the screen (see Figure 18-16).
Figure 18-16. This DISPLAY block will display Pressed if the variable has a value of True. On the False tab, I place another DISPLAY block that clears the LCD screen and puts the words Not Pressed on the screen (see Figure 18-17).
