Parts
In this video we take a quick a look at some of the parts we used to make Bit-zee. Although we highly recommend you create your own Bit-zee using parts from products that people would otherwise throw away. Created by Karl Wendt.

- Does the type of arduino matter?(3 votes)
- not really. Arduino Uno is approx. $20. If you want a mega, which had more pins, that's a least $60(4 votes)
- can we create this robot w/out solder? thnx, 4ironman(3 votes)
- it would be hard, but you probably could.(1 vote)
- At, what's an arduino? 2:13(1 vote)
- An Arduino is a multi-functioning chip that processes information and allows you to program it on your computer. It's a neat device really. For some experiments you can visit Autodesk's website and they have a branch for creating boards with components such as these.(2 votes)
- Where can you get an ardwino?(2 votes)
- Also, Radio Shack and Amazon.com both have them available. When looking for parts for a class, I think I found Amazon.com to be the best price (~$22).(1 vote)
- Could a class do this?And is it even a good idea to have one do it?(2 votes)
- I think a class could if you explained everything simply to elementary students. Middle school, high school, and college students would probably need less explanations. It would most likely inspire students to become inventors or a scientist. That is why it would be a good idea.(2 votes)
- can you do this in two weeks or about a month?(2 votes)
- it depends on how much time you work on it!(1 vote)
- How much does all of this cost?(1 vote)
- Hello Sharva,
Depends how you do it. New parts can get expensive. Salvaged parts from old appliances and broken toys are nearly free.
When I started out in electronics I truly enjoyed tearing things apart to see what was inside. Perhaps you could do the same.
I'd like to leave you with a few links including

- The L298N motor driver modules look different when I google them. Do I specifically have to use the Solarbotics L298 Compact Motor Driver Kit? Or can I use other L298N ones?(1 vote)
- all of the l298n motor are the same.(1 vote)
- Does anybody have an idea of the approximate cost of the parts necessary for this project, assuming one doesn't just have any of them lying around but needs to buy everything new?(2 votes)
- Depends where you live, robot part are about twice as expensive in Australia then they are in America. You're probably looking at $40. (he might tell you in another video).(2 votes)
- how much will it cost to make one(1 vote)
- It actually depends on what things you use. I don't really know how much it actually costs, though.(1 vote)

OK. This is all our
parts all laid out for the Bit-zee bot, the things
that you'll need to make one. Now you can make yours out
of a broad variety of things, and we highly recommend
that you do that. The only thing that you really
have to have is the Arduino. Everything else you can
switch out for other things. You can use different
types of batteries. You can use different
motors, et cetera. I'm going to go through
what I've got here and where the
products came from, or where the parts came
from, I should say. And then we're going to start
to put a Bit-zee together on this board so you can
see how it's all wired up. But if you don't happen to
have two hair dryers that you can take apart, you can either
go and buy two electric motors and get some wheels for them. Or there's a variety
of things you can do to solve that problem. So again, these are two
motors from our hair dryer. You can see the hair
dryer blower fan there. And underneath that
is a sheet of Lexan. It's a stiff plastic
that's really resilient. And that sheet of Lexan,
it's easy to machine. You can drill holes in it
and do stuff like that. So it's going to be used for
mounting some of our devices. And you can get
that at a hardware store for a few dollars. And this is a universal
remote, and it can be gotten at
Target for around $8. And we're going to use that
to control our Bit-zee bot. And then we've got
some electrical tape and different 22-gauge wire. And then we have
some solder here. We'll use that to make
our solder connections. Just like if you saw the video
for the motor controller, it was used to
solder that together. And this is a motor
controller, which will allow us to
control the speed and direction of our motors. And this is our Arduino. It's our microprocessor
that we can plug into-- I should say a
microcontroller that we can plug into our computer
and download code to it to get the motor
controller and other things to function the way
we want them to. So this is a breadboard, and
it's used for prototyping. And we're going to show
you how to wire it up and how to connect different
electronic components to that. And this is our digital
recording module, and it's for basically recording
sounds and playing them back. And we're going to use the
Arduino to trigger that so that when the little
bot drives around it can make some sounds. Of course, these are
just double-A batteries, and they're going to go
in this battery holder. The double-As are 1.5 volts. But when we connect
them in series together, they're going to be 12 volts. So that'll be great for
powering our motors, because they want to run on
a higher voltage than 1.5. And so we have our
different transistors here that we're
going to use to do some switching in our circuits. And we've got some three-color
LED and some screws and nuts and then a bunch of resistors. And these are 330
ohm, 10K ohm, 220 ohm. We'll go into the details
on that kind of stuff later. And then I have some of the
board of our alarm clock radio, so we're going to use some
components off of that board. And we've got our
coffee maker here. Or I should say
our coffee carafe; it's just the holder
for the coffee. And we're going to use
some of the components on this for the Bit-zee. And then we have some-- over
here you can see some zip ties. And so we also have
an-- we're going to need a infrared
sensor for the Bit-zee. And that infrared
sensor will be used for sensing from
the remote control. And so it looks like this,
and we'll have one of those as well.
