 Can you get there? Oh, hold on. The LED pop. See where my finger is? Put your finger down. Hold that right there. Okay. And I am going to... I don't know if I can take it with one hand. Right there. Bring it back. The LED went on. Oh, there. See? Do it again. Perfect. Can you just put it right here? There you go. It jumped. So, both my kids were recently involved in a science fair. And my son's project was on using sonar to detect blind spots on a car. And as you saw in the video, you know, he did a lot of work himself. He needed a little more assistance than my seven-year-old daughter. He's four. But he really did hook up a lot of that himself. Obviously, I uploaded the code and actually was going to write my own code for that. But the example code I found online worked for exactly what we were doing. And so I uploaded to the Arduino. But as far as creating the thing, as you can see in the video, you know, I basically... I would plug in like three wires and go, look at these. Okay. And I'd unplug them and say, you plug them in now. And he did that. And he did a great job with his little tiny fingers getting them in there. It was painfully slow to watch, but he did it. And then I helped him obviously tape things down. But basically what you saw in the video is what he did. That's why I recorded it to show, you know, even though he needed a lot of assistance through it, he did do it all himself. And as far as his presentation, he did a great job considering he's four up in front of people. The original situation there was going to be people coming around to table to table. And I wanted their projects to be very interactive. In the end, they changed it last minute to be you're up in front of everybody presenting, which was a little different for him. Well, not different for him. He does that quite often at school, but it wasn't what we originally were planning. And he did a wonderful job. Very, very basic explanation. He basically just said, this is a car. It uses sonar, which is sound to detect when something's there and lights up an LED. It's basically what he said in his presentation. It wasn't much more than that. But he did a great job. And I just wanted to share this video of him getting it all ready.
