One important source is the “block help” in the lower right corner of the
environment. Select a block you have questions about, and make sure the “?” tab
is selected, and a very short help text will show up there. Click on “more help”
and a whole new world of in-editor help is revealed (you can also get to this
from the menus, Help->Contents and Index).

I could some expert advise.

There is none - we’re *all* new at this, but some of us have been new at it
slightly longer ;-). *Nobody* is an expert yet, so if you discover something,
let us know.

Using the Ultrasonic sensor, detect motion and then randomly play
a sound file (one of several I have setup). Continue to monitor with
this sensor and detect motion again and play a different random file.
|
Drop an loop onto the programming sheet. Within the loop, make the first
block a Wait for the US sensor to be less than, oh, say 100 cm. Now generate a
random number (from the Complete pallet), followed by a multi-case Switch
structure (drop a Switch after the Random block, and then in the Switch
configuration panel set control to variable, type to number, uncheck the display
option “flat view” so it drops into a tabbed view. Now click on the “+” button
in the upper right corner of the configuration panel to add a few more options).
In each of these Switch tabs, drop a Sound block that plays a different sound
file, and finally set the Random block to generate a number from, say, 0 to 3
and wire this number into the Switch:

| Thanks for the fast response. This is exactly what I was looking for. Is there anyplace (website) where the actuall code can be saved for others to download? (18 years ago, 5-Jul-06, to lugnet.robotics)

| I have looked over the route you posted and have some questions. It looks like you have 4 branches on your switch. How did you get it to compress the graphic of this part so that it doesn't fill up the worksheet? Thanks for your time, Tom (18 years ago, 5-Jul-06, to lugnet.robotics)
