Mr. Dog Poop: Well, yeah, you can get them lit up. You can get them.

Jeff: Should just be a positive, right?

Mr. Dog Poop: So, there’s a jumper there.

Jeff: I need two hands to do this. There we go. I got a light on.

Mr. Dog Poop: You got a light on.

Jeff: My experiment worked.

Jeff: Yeah. I hooked the bottom up to the negative up to the lights. They light up.

Mr. Dog Poop: Well, you've done more than me.

Jeff: I got an LED light going.

Mr. Dog Poop: I bypassed the switch, hooked it up directly. Put a jumper in here, have the speaker in here and go through the LED. I mean they have it going through an LED to the speaker, but that's still should work. I feel like somebody gave me dead batteries. I’ll try what you tried.

Jeff: Yeah, I think that's the simplest battery test, right? Just positive to positive, negative to negative. And it lit right up.

Mr. Dog Poop: Well, I'll tell you what. Oh, I'm using the speaker wire. Okay. That's better. All these wires are confusing.

Jeff: They are. And I do think I've actually got, let's see, 1, 2, 3, 4, 5, 6.

Mr. Dog Poop: All right, so the batteries are good.

Jeff: I think I've matched the picture and it's not on.

Mr. Dog Poop: It's not working.

Jeff: No.

Mr. Dog Poop: So, that was just somebody put that together for the picture.

Jeff: They wanted to make it look easier than it was for dummies like me. At least I got a light to work. All right, come on. I just need a musical note out of this.

Mr. Dog Poop: I wish I had a schematic of the whole board. It says one and two are the switch. No, that's 30 and 31. One and two are the batteries. One, two battery. The battery goes to the switch and then it goes to 39.

Jeff: 39, that's all the way down here. I've got that one plugged from the on switch to 39.

Mr. Dog Poop: 39 and then ground is 40. So, this is negative. Why is this one to 36? Should go to 40.

Jeff: Oh boy.

Mr. Dog Poop: 40, 43, 41, 40. We go to 40. 39 and 40. And then, oh, also to some diode and then to LEDD five.

Jeff: Something's supposed to be in this touch plate. What is this for?

Mr. Dog Poop: You’re going to be able to do some different sounds because it's like a little antenna. So, you're going to be able to like a metal detector. There's a push plate here, which is just a kind of a switch. The resistors, which are going to change the volume levels. You got a transistor, variable resistor. So, interesting thing on it. But yeah, that's a potentiometer. So, that's just a variable resistor. I don't know what this melody thing is. It's got to b, some chip with melodies in it. But the question is, there's a different experiment for the whole bunch of them, but what's number one? It just has 30 and 31. One and two. One goes to, I mean, I'm going to follow experiment one. Take this thing apart.

Jeff: I made the speaker make a noise. The keyboard is not connected. I'll hold it as close as I can. You probably didn't hear it.

Mr. Dog Poop: One is super simple. Super simple. It's got a schematic here. It also says something, complete all wire connections indicated by a sequence switching on the LED light by switching off the LED will extinguish you can change another LED yourself, blah, blah, blah, whatever that means. But 30 and 31 are the switch that's right here.

Jeff: All right. I'm going to try to wire 30 and 31.

Mr. Dog Poop: The battery should go to 11 and 12. Wait, that doesn't make any sense.

Jeff: 11 and 12 is an LED light.

Mr. Dog Poop: Yeah. That's what it's showing.

Jeff: Are you using the LED light to turn the on or off?

Mr. Dog Poop: Simple LED circuit it says. So, remember what you did with the battery?
