Introduction to TinkerCAD Circuits

Introduction to TinkerCAD Circuits

13.Jul.2021

welcome to in this video are gold today
with this video is to introduce
Tinkercad which is a piece of software
done by Autodesk and the goal is to
provide a easy to use way of doing
certain experiments online this
particular product Tinkercad has many
different functionality and the one
we're going to focus on today in this
video is electrical side of it and our
goal is to introduce the basic
instruments that are available on this
tool as well as how to build simple
electrical circuits using this tool so
let's go ahead and start at the
beginning and talk about where can you
find Tinkercad as the name implies you
just go to tinkerer chad dot-com and you
will get to that side if you have not
already registered when you get to this
point you're gonna have a sign-in button
and click on it or you can either use
your email and username to get into it
or you can use your Google sign-in with
Google so I'm going to use this one and
since I've already signed in all my
information is available in there and
it's going to sign me in if you don't
have it you have to go through and
create your account and all that these
are all free and instead of the cat
stands for computer aided design as you
can see I've been playing around with
this thing and I've got some mechanical
design that's another feature it has it
allows you to do three-dimensional you
know 3d design for printing yet but
today we're going to focus on the
circuit side of this so once you have
created an account you simply click
click on create new and it will create a
new file for you
so since I've already done this I'm
gonna click on this one this is a
pre-existing I haven't really done
anything with it but that's created in a
while ago so once you save your document
the next time you come back it's there
and you can just able to say tinker this
which would be it opens up the screen
and you can start working with it so so
far what we've talked about is basically
what how do you get to tinker cat and
the fact that you need to create an
account before you can log in and you
simply can use your email and whatever
password it is a two-factor verification
so it's gonna require you to send you
that an email or send you something in
the phone on your phone to validate that
you who who you are saying you are you
actually are other than that is a very
simple process to create an account and
best of all it's free and it's pretty
the performance is really good as well
so the next thing I wanted to do is talk
about kind of what would you see here so
when you get here you will have of
course some basic tools about rotating
things if you have some component here
and you are rotating this button allows
you to do that if you want to delete
something you can either press the
delete button or you can press this
garbage can looking thing and then you
can annotate you can put some
information or you can hide stuff and
then over here this device we won't get
to it in this video but this device
allows you to embed an Arduino a
microprocessor board if you if you want
to use them or do we know to do
something then you can write the code
build the circuitry here and then when
you finish you can download that to a
physical Arduino use it but that's not
our goal today our goal today is to
learn about what components generally
what components are available focusing
on the resistor only and also learn
about how do we get to use the power
supply and the multimedia and the proto
ports or the breadboard they call it
breadboard
proper citizen interchangeable love
things so if you look at it so so far we
talked about kind of the brand new items
and there's a simulation we definitely
gonna get to use that so once you build
yourself that you can actually see and
run to see if it does what you wanted to
do which is a really nice feature you
can share it you can export it and all
that so let's let's go what I'm gonna do
I'm gonna do select on the components of
just a basic one I'm gonna select all
the components that are available so I'm
going to look at everything that they
have and as you can look up here they've
got basic electrical components diodes
and caps different kinds of capacitors
inductors and resistors all our focus
today is going to be on the resistors
and then there are other nice sensors
for example there are photo resistors
for our diodes they have ultrasound
distance measurement IRS so you can
simulate a lot of different things
keyboards if you want to do that if you
want to use switches the switches are
available all that is very nice and easy
to use and then they got the LEDs here
all kinds of LEDs and light bulbs and
all that as you want to use them and
then fine and then some display board
display this is called the 7-segment
display LCDs and then some different
kinds of bread boards we're gonna use
this particular bread board here so saw
one beer here up just gonna select by
the weather if you like something and
you want to put it on your board all you
do you click on it and then click over
here and brings it in and what we're
talking about every time you put a
component on you're working the desktop
which is right here it also gives you a
product it gives you a kind of the
properties is called the properties
table I believe and so it kind of tells
you what it is it says this is a small
breadboard you can have a larger one if
you want but we're gonna have the small
breadboard is simple that's fairly for
what we're gonna be doing here
and it tells you the only property gives
you for this one is a name South just
basically send
reward one maybe I have a second one so
that's pretty much it as far as the
protoboard is concerned then I think as
I was mentioning there are rarer
Arduinos you can pull in and use but to
skip those we want to focus on this mold
this is the multimeter and a component
as soon as I clicked on it you know this
one came out so I'm gonna put it right
here and then I'm gonna click on this
one - this is the power supplies as soon
as I click on that I will get power
supply to come in here so so now let's
go ahead and go back and talk about
these oh well let's let's put one more
component in here - so let me go back up
here and get the basic it's gonna put a
resistor in here as well okay now now
let's go ahead and explore each of these
individually let's start with the power
supply so so the power supply is
basically a glorified battery okay so
what you could do is basically since you
gave it a name I can say this is a
source you can call it whatever but I'll
call it a source of a lot of time for
electrical stuff you say this is a
voltage source so the reason acronyms
abbreviations like es to tell you what
it is they're looking at and then what
voltage do you want to set it out I'll
say okay 5 volts sounds like a good
thing and this basically is telling you
what the maximum current you want to put
out of here and 5 5 amp is more than
enough for what we gotta do right now so
that's the power supply it's job is to
produce different voltages for you in
and then this is a this is a multimeter
so if you if you think about it this
actually is three instruments in one I
can run it as an ammeter I can run it as
a voltmeter and I can run it as a
resistor notice as soon as I clicked on
it what happened I got a property sheet
coming up here and it says okay you got
a mall time you know what do you want to
call it let's say we're gonna call it a
meter or whatever reason and then and
then it says okay do you want to use it
as an
Peter do you wanna measure current do
you want to use it as a voltmeter
measure voltages or do you want to use
it as a ohm meter measure resistance so
those are the choices you have this is
the property sheet here so I think some
of it I can show you pretty quickly for
example let's say I remember we set this
one to 5 volts so if I want to measure
to see what this is all I have to do
I'll just go to one so you notice that I
go over a terminal it highlights it and
then also tell me so I'm just gonna
basically
hold the left button on my mouse down
and bring it to this one and click on it
there is now I have a wire from here to
here and then I'm gonna put a wire from
here to here now notice I maybe I
shouldn't have done that but I did it
backwards which means now if I set this
one to a voltmeter and we change that
one to a multimeter
notice how this thing change to the
world so if I use it as a voltmeter I
set this one to be 5 volt but that would
be plus from here to minus here but I
connected it backward to this one so I'm
expecting to read minus 5 on that screen
so how do I make this thing do something
and that's where the similar start
simulator comes but it comes in this
basically starts and stop the simulator
which Missy said ok I have a circuit
here go ahead and try and see what
happens so if I run this thing and you
notice this one has got 5 volts and
since I connected it backward here I'm
getting a minus 5 volts let's go back
and correct this so what I need to do is
basically get this out of here oops I
can't do that okay we're gonna take
their black side from the power source
no one do that either so let's clean
this up get rid of this wire as well
we're gonna take the red one connect it
to the red one we're gonna take the
black one connect it to the black one
and now if I'd run my simulator to see
what's going on I get five life is good
okay so hopefully now you know how both
me their works
now M so wolf Peter is like infinite
resistance so I can connect it directly
across the power supply nothing bad will
happen but if I stop this and I want to
use this thing as an ammeter then I put
it on amp but amp you can put it
directly across the power supply because
that would cause the power supply to
short and then bad things will happen
you cannot short put a zero ohm across
or a piece of wire across the plus and
minus of the voltage because that will
make the power supply try to produce
infinite infinite current which causes
it to give you error so instead what I'm
gonna do is I'm gonna take this wire
oops let's go ahead and get rid of this
what escape will basically stop you from
drawing wires if you if you're drawing
wires and you don't want to stop it just
press the Escape key it's gonna get rid
of that so what I'm going to do I'm
going to take this resistor and we're
gonna bring it down here and I'm gonna
take a piece of wire and by the way
typically in electrical circuits we want
this lines to be either horizontal or
vertical although it's not the end of
the world it is not but they would look
then would frown on you doing that okay
so so instead of instead so I'm gonna
find out how the ammeter is then I have
to take this wire that goes through here
and direct the current from oops here to
the ammeter plus side and then so I want
to force all the current to go through
the ammeter and when you're using
ammeter the resistance of a meter is
equal to zero so it's like just a wire
inside okay and then I'm going to take
this over here back down and notice I'm
trying to try and to do either a
vertical or horizontal or 45-degree for
the factory cannot they're almost alive
the reason for doing this is a lot
easier to follow if you just randomly
draw wire we call it a rat's nest
because you're not wires quick everybody
really hard to follow okay so now I have
a circuit and remember I've got a so you
remember from our history the brown is
one black is zero so that's ten times
red is two which means is 10 times 10 to
the power 2 so this is one thousand ohm
so if I run this thing the current
through here should be 5 volts divided
by 1000 which is 5 milliamps so let's
try to say forget that so we're going to
start the simulation again and sure
enough notice it's 5 milliamps and that
now one of the things let's say let's
say I want to do multiple things at the
same time with this one I'm going to
measure the current I want to measure
the voltage I want to measure the
resistance and all kinds of goodies like
that so what I'm gonna do I'm gonna come
over here and grab another one of this
and then I'm gonna come over here and
grab another one too and actually what
I'm going to do is I want this one to
measure let's say so so let's go back
and rename this this one is gonna
measure amps so we're gonna call it and
leader so we remember what might as well
this one is going to measure the voltage
so we're gonna have selected to do
voltage and we're gonna call it volt
okay so now you do the same thing click
here with the right button go series the
positive the positive is over here so
there it is and my negative is over here
and since we've got 5 volts what should
be able to see 5 volts in a voltmeter
now maybe at the same time and this is
not at this we're gonna do this but
we're gonna come back and talk about if
that is really the right thing to do
I'm gonna call here and I'm gonna tap
this one the third function I can do
which is resist us okay so this is
called a home
you know it's gonna all be there or
whatever it's gonna measure the
resistance so we'll just polish
resistance and notice that the R is
selected here now what I'm going to do
is again once I'm going to do is take a
piece of wire put it over here you can
do that with the herbs and notice if you
don't go to these connections you will
you will not make the connection it just
keeps thanks so let me go ahead and do
it one more time up here you've gotta
get that red button red cup red sucker
up squirt to come up otherwise it's
really done making a connection okay
people violate their rules and I go
diagonally up that now I should be if I
turn this on
I should see the value of the resistance
here
I should see the voltage here notice the
voltages across this but notice the
ammeter is broken into the circuit so I
can measure the current going through it
so I should see 5 million up here should
be 5 volt there and if everything works
this is what something we gotta careful
everything works here
I should see one killer so let's see
what happens oops
so so now what so everything looks
pretty good pretty good
we've got oh oh yeah we got we got all
kinds of problems here so we've got a
wrong value here oh this is a nice oh we
must have a problem here and the problem
has to do with this o meter here you
cannot measure resistance in a circuit
because when you measure the resistance
in a circuit you're actually putting
this whole meter across all of these and
it's changing the value so you're
drawing more current than this is
capable of giving us so instead of
giving us 5 volts is
- give us five it's giving the maximum
we can and since we said the maximum of
five Millions
so the moral of the story is that you
cannot measure resistance inside a
circuit you have to break the circuit
you have to take a resistor out before
you can use it as a normally turn
so let me fix that let's stop this thing
get rid of this thing so I'm basically
taking my ohm meter out of the circuit
because that because it's not infinite
resistance it's got a cost problem and
also because this resistance is going to
be in parallel with all that so all of
those things together will cause a
problem so it's going to start the
simulation again and now everything
looks good so we've got the five million
because we've got five volts through
going 1k five volts divided by a
thousand is 0.005 amp which is 5 million
milli amp is 1000 M is 5 most everything
looks good now notice that when we are
measuring infinite resistance this thing
says is Meg ohms so that must be
whenever you see me going with no number
on it means you have an open you don't
have anything across now let's go ahead
and remove some of these to see if we
can measure so we're gonna take our
resistor out of the circuit and try to
measure it so what we're going to do is
this is my ammeter and might as well
kind of play with this a little bit Oh
so we can also rotate this sometimes
it's easier if you rotated the
components are easier to get to with
your wiring so we're gonna take this put
it over here take this and put another
wire here now we're gonna start the
simulation and sure enough it tells us
is 1 kilo ohm you know this and of
course this is the circuit is broken you
have zero ohm in here since this is
floating this you know what's there and
but this one is still supplying 5 volts
but since nobody this is open and no
current can flow through it you got a
zero amp coming through that
the last component we want to cover in
this is this proto board now when you
use when you're using Tinkercad
you don't need the proto board but when
you're actually trying to build this
thing in the physical world you will
need this because the nice thing about
this is if you want to connect ends of
two components together this protoboard
allows you to do that these are
connected in a certain way and I would
like you to experiment to see which one
of these are connected with what but you
can the hint is here notice as I go over
it the hint is doing the diagram is
shows but I don't want to give it too
much away so what we're going to do is
basically if you want to know what is
connected to what you put one wire in
this hole and you put another wire in
this hole and you run the simulation so
start a similar to zero which means
these holes are connected to each other
so now I said well I'm not sure let's go
ahead and see if I were to take we stop
the simply have to stop the simulation
before so if I take this and go to the
next hole are they connected to each
other
so if I start a simulation so oh no the
remebered may be all good no number
means it's open there's no connection
there's a resistance is infinity so
experiment with down and see if you can
convince yourself which hole is
connected to which hole so so so far we
could talk about that so typically when
we when we build this thing for example
I'm not sure what I did with my resistor
so let me so typically if when you are
doing chips which are the needs we put
them on the board like this this way if
I want to make a connection to this leg
to this leg I can basically take a piece
of wire and go here now these two are
connected to each other all right I want
to have another wire connected there it
is connected to it too so that's kind of
how they use this thing so to make it
easier to make connection and break
connection so for example if I got a
resistor and put my resistor here and I
can make connections
resistant like on any of these holes
missed a little nicer to do it this way
instead of the way I was doing it for
example if I wanted to this this if I
whoops
everybody can get rid of all these I get
see how that messy really quickly so let
me go ahead and get rid of all this
stuff and let's go to draw a wire from
here to this hole and another one from
here to this hole and it's kind of makes
it nicer just to be able to have its own
point of connections and stuff lumping
them all on top of each other like I was
doing and also the board allows you to
organize things in a more orderly
fashion so if I do a simulation once
again you see is 1k here and typically
let's stop right here so what we've done
and this was an introductory video just
showing you how you can use power
supplies how you could connect things
together using the wires and how you can
use voltmeter either asked multimeters
measuring amps remembering that amps you
have to break the circuit and put the
ammeters in the way like I did that
earlier and you can measure you can also
use the multimeter as a voltage
voltmeter you can use it as a ohm meter
and measure resistance okay that brings
us to the end of this video make sure
when you're looking at this video there
might be some comments about Corrections
or clarification so read the description
of this video before after or before you
watch it if there's nothing there then
that means everything is ok thanks and
look forward to the next video
