- Hi Stephen,
The Spout is a good place to start electronics / mechatronics / robotics. The design is simple because it's important that you have successes along the way.
May I recommend Instructables.com for more ideas about robotics.
These are the parts you're going to need to build your Spout bot. We've got lead free solder here. This is going to be used to make metal connections and conduct electricity and hold our circuit together. We've got some hot glue. That's a hot glue stick. We'll use that to hold the parts together that don't need to conduct electricity. We have two resistors here. These are 41 ohm resistors. You can use anywhere from around 40 to 200 ohms. It kind of depends on how bright you want your LEDs to be and what types of LEDs you choose. We've got our LEDs here. These are two water clear blue LEDs and four paper clips. There are two 1.5 volts to three volt motors, which work well with our batteries, which happen to be 1.5 volt double As. And together in series, they are three volts. Then we have two bottle caps from water bottles, some shrink wrap tubing. This comes in a lot of different sizes and colors. We've chosen 1/16 inch and I believe 1/8 inch tubing. And we've got some sliding lever switches here. I should say, sliding switches. These are sliding single pole double throw switches. We've bent one of the throws out of the way so it's just a single pole single throw switch. So we're going to use those as on/off switches. And then we have single pole double throw lever switches. And we're going to use one pole in both of the throws for those. And then we have wire. And this is 22 gauge insulated wire. We've chosen a number of different colors-- green, blue, red, yellow, and white. And basically, we chose those colors because they're going to show up better in the video when we put them on top of our battery holder. And this is our double A battery holder. So those are the parts that you're going to need to build the Spout bot. Now we're going to talk about the tools.
