Jeff: With the red?

Mr. Dog Poop: Yeah. But if you did it through the switch, that would be experiment one. I don't know how that's going to play music. Read switch, same thing. So, it's not a music board, it's an electric board. So, you just hook up this read switch. And how does that read switch work?

Jeff: I wonder how many wires I can fit into the battery. I'm going to try something in.

Mr. Dog Poop: It looks like it has simple wiring circuits. So, the fact that it's playing a piano. I don't actually know if these keys actually do anything.

Jeff: I'm not sure if it does either,

Mr. Dog Poop: Because these are simple circuits to learn about switching. So, let's say I use this potentiometer, right? So, I hook it up to the battery and then hook up, the center should be the variable point. Hook it up to the red LED and just hook it up here, hook the other side up to the other side of the LED that should go on. And then as I turn this up and down, I can make it bright. See that, Jeff? Look at what I did.

Jeff: Oh, you make a light brighter or dimmer.

Mr. Dog Poop: Now, how that relates to the music keys. I thought we were going to be playing a piano.

Jeff: Yeah, I'm starting to think you're right that the piano keys are just kind of dummy.

Mr. Dog Poop: So, I think this is age three plus.

Jeff: I think it's eight plus.

Mr. Dog Poop: Yeah, I don't believe it. Eight-year-old will get bored with this. So, this is probably three plus.

Jeff: Yeah. Oh, you know why it's not three plus? Because you'd be finding these in the baby's diaper.

Mr. Dog Poop: In the baby's stomach. I mean, these are pretty cool wire diagrams. This one has all the LEDs in parallel through a switch, hooking up the batteries. That's your touch control music musical doorbell.

Jeff: That's the one I'm going to try right now.

Mr. Dog Poop: You're making that right now?

Jeff: Yeah. Experiment 15. Is that the one? Oh no, that's manual control.

Mr. Dog Poop: It says there's a magnetic controlled musical doorbell. Which one are you playing? 17?

Jeff: I was going to do 15.

Mr. Dog Poop: Okay. Manual control. Musical doorbell. I'll do touch control doorbell.

Jeff: All right.

Mr. Dog Poop: All right.

Jeff: Let's see here. Two to 30. Alright, I'm going to plug all these things out and start from scratch.

Mr. Dog Poop: I should probably just rip this thing apart right now and find out if these keys actually do anything.

Jeff: We definitely need to check before the end.

Mr. Dog Poop: Why make it like a piano if it doesn't play?

Jeff: I feel like that's another reason that like, kids would want to play this, you know, not just look at like four blinking lights.

Mr. Dog Poop: So, it looks like positive should go to 23.

Jeff: 31, 27.

Mr. Dog Poop: Positive goes to 23. Oh, no, I'm into the melody thing, so whatever that is.

Jeff: Just want to get one noise. Just one noise.

Mr. Dog Poop: I swear I just hooked it up to the battery, but it was hooked up to the LED. The positive goes to 23, 22 goes to 24.

Jeff: Now, they've got them all lumped together. See if this makes sense, when it's two to 30 and then it's 31 to 20 to 27 to 24 or to four, whatever, does that mean just continue to wire those all together?

Mr. Dog Poop: Hold on.

Jeff: I don't think my senses made sense.

Mr. Dog Poop: Okay. So, I'm looking at the little diagram here, the little schematic that pretty much tells you how to do it because it shows you the actual wire. So, the speaker is four and three, and three goes to 21.

Jeff: So, 27, 4. I need a longer wire. There we go.

Mr. Dog Poop: What the heck's 21? Let's see. 21.
