Scratch

The motor blocks are for controlling the Lego WeDo software.
([slider] sensor value) and <sensor [button pressed]> have to do with sensor boards (there's a whole section in the forums).

Like the (join (hello )(world)) block could be used like this:
[when flag clicked]
[ask [What's you're name?]]
[say (join (Hello, )(answer))]

Not many people actually gave you examples on how these can be used, so I'll do that:

When green flag pressed
Ask 'What's your name?'
Say 'say (join (Hello, )(answer))'

It's obvious what that does.

When green flag pressed
Ask 'What's your name?'
Set counter to (0)
Repeat (length of (answer))
Change counter by (1)
Add (letter (counter) of (answer) to list (any old list)

That adds each letter individually to a list.

When green flag pressed
Forever if <sensor button pressed>
Say 'The button is being pressed'

Tells you whether the button on the picoboard is being pressed.

And I really can't be bothered to do any more. Sorry.

Thank you for some of the examples, WF. (Ya don't mind if I call ya that right?)

No, that's absolutely fine.

Yo Ralphjos! Hope you are well. I teach classes using PicoBlocks (a version of Scratch) and PicoCrickets which is basically the Lego WeDo system paired with the application.

That system comes with many project ideas. I made a remote control (via wires) car with a horn and headlights. We also made door alarms, musical Playdoh, moving sculptures, moving windmills, a motor driven optical Illusion, a light sensor that made music, a starting light for our lego race car track, all kinds of stuff! In general terms, I love the motor cause you can take your programing off the screen and make stuff happen in the real world. Just like Scratch, the possibilities are almost endless.

For example, you could make program that could read someone knocking on a locked door and if they used the right secret knock, unlock it (although that would be tricky.) I used to fish a lot and often wanted to get up right at dawn. You could make an alarm that ran off a light sensor attached to a window and then turned on a radio when the sun began to come up (unless clouds made you sleep late heh.) Because I teach with this stuff, I have access to a ton of motors, brains, etc. Some day, I am going to combine several sets and make a walking, talking robot. It will have to be simplistic but, well, some things you just have to do because they are cool, you know? PS.. I am not trying to talk you into buying anything. I don't work for Pico or Lego, lol. But it is a neat system that most people seem to have barely even begun to put to good/cool usage, from what I've found. Peace.
