How does the LEGO Smart Brick work? if you're confused about the new LEGO sets with sounds and lights, I don't blame you! There's a whole LEGO Smart Play ecosystem to get familiar with, and hopefully this video breaks down the basics: the Smart Brick, the Smart Tag, the Smart Minifigure, how the sensors communicate, the battery life, and more.

This demonstration uses the LEGO Star Wars Smart Play All-in-One sets that launch on March 1. All-in-One means it comes with the Smart Brick and the Smart Brick charger. That implies to me that there will be smaller sets or pieces sold separately in the Smart Play system sometime soon.

00:00This little brick is causing a lot of controversy.
00:02But before you jump to any conclusions,
00:04give me a chance to explain how the LEGO Smart Brick actually works.
00:08LEGO packed a ton of tech into this 2x4.
00:12Not only is there silicon, the smarts, but there's all sorts of sensors.
00:16We have motion, we have lights, we have even a microphone that detects pressure.
00:21But alone, this thing is actually kind of useless.
00:24You're going to need some other new LEGO pieces to make the magic happen.
00:27And I think the best way to demonstrate it is using one of the actual LEGO Smart Playsets
00:32that's launching on March 1st.
00:34Recognize Palpatine's Throne Room?
00:35In this LEGO Smart Playset, you're going to get a selection of Smart Tags.
00:40Have a lightsaber Smart Tag here behind Luke, another one behind Darth Vader,
00:45and I'll turn around Palpatine's Throne, and you can see one that's a chair.
00:50The RFID Smart Tag is what tells the Smart Bricks chip what to do.
00:55So if I put this brick on top of a lightsaber Smart Tag, this brick is essentially now a lightsaber.
01:03But who is controlling the lightsaber?
01:06What color should the brick be?
01:08What sounds should it make?
01:10Introducing the Smart Minifigure.
01:12This symbol on the back differentiates a Smart Minifigure from, you know, your average Minifigure.
01:17Information from the Smart Minifigure changes how the Smart Bricks react to the Smart Tag.
01:22The Minifigure almost takes precedent.
01:24That is what the Smart Brick and Smart Tag are looking for to really bring out the personality in play.
01:30We have another lightsaber Smart Tag there, but because it's now closer to Darth Vader,
01:38we get a red lightsaber, complete with my favorite whooshing lightsaber sounds.
01:45I'll show you one other example.
01:47Here we have the Smart Play X-Wing set.
01:50That is an X-Wing Smart Tag.
01:52So if I put a Smart Brick on top of the X-Wing Smart Tag, the Smart Brick is now
01:57an X-Wing.
01:58So the brick is giving us all the motion and the lights, but again, it's that tag that's telling it
02:03what to do.
02:03So you could put that tag on something that is not an X-Wing, and it will still give the
02:09lights and motion of an X-Wing.
02:11So lots of creative options there.
02:13Even on this table right here, there is maybe a dozen Smart Tags.
02:16It's the chip inside of the Smart Brick that's deciding what should get priority based on proximity.
02:21So just this one Smart Brick could be a lightsaber, be an X-Wing, be a TIE Fighter.
02:27And it could do so for about 40 minutes of active playtime.
02:31A little sound effect will tell you when it's time to charge,
02:33and then we're going to drop our brick right here on the wireless charging pad,
02:37let it juice up so that it's ready for more play.
02:39I have seen your comments, and I think a lot of your questions and concerns about Smart Play and the
02:44Smart Brick are valid.
02:45I do think it kind of is a case of needing to play with it to understand,
02:49and maybe being a little bit more willing to exercise your creativity.
02:53Be sure to let me know if you have any other questions about the Lego Smart Brick.
02:57Now get out of here. I have a lightsaber battle to get back to.
