Introduction to Tinkercad Circuits & Breadboarding

13.Jul.2021

hi this is mr. wofully here and today
we're gonna go through using Tinkercad
circuits to build our very own circus
and we're gonna be looking at how to add
components you know some power sources
resistors LEDs some basic circuits and
then how bread boards work know not to
cut your bread this is something
different and how to simulate our
circuits and if we have time we'll look
at parallel series circuits okay so
let's get started
open up Tinkercad circuits and to get to
your home page again you just click on
that logo on the top left the Tinkercad
logo and my default goes to 3d designs
we want to go to circuits just right
there on the Left we'll click on that
and we can create a new circuit just
like so so like I said before the first
thing we wanna what any circuit needs is
a power source okay so I'm gonna type in
power here on the right and we know it's
on the right this is where all our
components are by default it's just the
basic ones we can go at all if you want
to show all the ones that will show up
there so I'm gonna type in power kids in
order to start a circuit up we need to
have some sort of energy source or power
source and here we had on the four
batteries okay and we have different
options here you know we have our 9-volt
battery a coin cell battery this is kind
of something that I've been your watch
some double-a batteries the cool thing
with all each of these notice if I click
on it we have our properties that shows
up right here we can give it a different
name and the cool thing of the double-a
battery we can add more batteries to it
we could even change it to triple-a
batteries and we can add a little built
in switch as well just pretty nifty one
thing you might notice well what is one
thing you notice that is common with
each of these three batteries that's
right
they each have kind of two areas or two
terminals is the technical term where we
can connect you know different wires
okay but before we get into connecting
different wires each of these terminal
each of the batteries have
two terminals one is positive one is
negative okay we have positive naked if
there's always a positive negative on
batteries positive is always shown by
the red negative by the black I'm just
going to keep the 9-volt battery and you
can rotate it using that rotate or just
hitting the hot key are there we go cool
so I want to start making a circuit here
I want to light up an LED so I'm gonna
go up to the right my components panel
here and type in l-e-d and we noticed
that all these different lights
different kind of LEDs show up I just
want the very basic one and no it's not
pronounced LED its LED and which stands
for a light emitting diode we'll talk
more about that in future videos what a
diode is so we have our LED right here
we notice that there is a bent kind of
like there and a non bent one if I pull
up my electronic components chart this
is kind of what an LED looks like we see
there's one leg that's longer ones is
that shorter this is the symbol for the
electronic schematic but right now is
when you focus on that one leg is longer
one shorter why is that well the longer
leg is called the anode side so if I put
my mouse over there
it's called anode the other one's a
cathode all that you really need to know
is that the bent leg or the longer laid
that's where the positive terminal the
positive wire will enter in through the
longer leg first okay so let's try this
something rotate this yeah like that and
so to make a wire into your cat's
circuits right here all you have to do
is click on where you want to make the
wire I can click to bend it I can just
move my mouse around and it follows it
so let's move it like so cuz I wanted to
connect to that positive side and you
notice that you can actually change the
color of it I like to go from the
positive terminal will make that red you
can also use the hotkey number two and
we'll go from
the cathode side hockey number one to
change a black just like so and we have
our completed circuit let's see what
happens if we start the simulation and I
serve simulation businesses there at the
top well we get some sort of explosion
that's not good so it's saying that the
current is too much current against just
the flow of electrons too many too much
electrons going on we have to slow that
flow down how do we do that
well we use something called a resistor
and a resistor well it does exactly what
it sounds it resists the flow so close
things down you can imagine it imagine
electricity or current like flow of
water and the resistor is something that
just flow slows the water down so it's
not coming as strong so I'm grab this
component and what I'm gonna do here
I'll take this wire and just hit that
delete button I'm gonna connect this
resistor right there and a resistor
doesn't matter which direction I could
connect it like that I could also rotate
it around connect it like that it makes
no difference
and I'll take my wire here I'm gonna
press that hot key to to make it red and
bring my water down here connect it and
start my simulation and we have the LED
is lit up that is lit and you might
notice here the resistor if I click on
it just like any other component the
properties properties panel comes up
here on the right and we have resistance
so we can change the amount of
resistance going through and we notice
right now we have 1k horseshoe no it's
not called over 2k ohms K ohm so that
that horseshoe which is the Greek letter
Omega last letter of the Greek alphabet
it signifies ohms or the amount of
resistance so right now 1 ohm isn't
enough we get that explosion again what
you can do just to have fun with it you
can you know keep on adding zeros what
happens to the light right so the more
resistance the last light point through
the LED which makes sense right more
resistance there's less electricity or
current flow of electrons going through
that LED
and we could type in something like an
all 400 and that will you know make your
LED lit up awesome
before we had K ohms K again just like
kilometers or kilogram
it means 1000 so that's one thousand
this year 1k ohm would be one thousand
ohms okay so this is just a very basic
circuit that we made here we have a
power source we have the resistor and we
have an LED and again if we were to make
this in real life we always want to have
a resistor with our LED otherwise it
won't explode won't be that dramatic
it'll just burn out which sucks okay
let's see if we can add a switch or a
button and then I want to talk about red
boards okay so this is you know the
circuits cool except it's always on so
let's go over here let's type in so it
and we have a nice slider switch right
here and I'm gonna delete one of these
wires and see if we can connect this up
cool so what I want to do here I want to
take my positive terminal and I want to
connect it to the middle and I want to
have this side right here the other side
connecting it right there so when the
switch is on the left side just like it
is right now it connects to these two
points right these two these two
terminals terminal one and the common
terminal when the other side is
connected it connects the common and
terminal 2 so let's try this out we
press start simulation and nothing
happens which is good that's what we
would expect to happen anytime you hit
simulate I want you to think about what
is should be happening here and see if
it actually happens like you think okay
cool so I switch it
it connects these two terminals together
I go over there what happens it breaks
that connection right we need to have a
continual connection in order for the
electrons to flow from one side all the
way together and hit then it turns it
back on
awesome so now I want to introduce Brett
boarding or the breadboard so we see
right here yeah this is cool the circuit
but if I were to make this in real life
it won't work out as nicely yeah I could
I could connect a wire to the end of it
a resistor and so on but if you look at
our components here and this is a kind
of a resistor in real life we have these
has a two ends these wires are led has
wires like that
we see that the ends of a this is a
9-volt battery the terminals look like
that it's hard to connect a wire to that
to do this to there and so on you would
have to use something called soldering
which is we melt this metal to the
different components that way they they
stay together but the thing about that
it's permanent so what we want to use is
something called a breadboard I don't
know why it has a name and here we have
different options mini we have a regular
one and a small one I'm gonna grab a
small one click and drag that on to here
great cool so just want to quickly go
through the breadboard and then I'm
gonna make this circuit with the
breadboard okay so right here we see all
these little holes and the cool thing is
what we could do we could take our
different components and we can pop them
into the holes okay what do you notice
here we notice on the top and bottom we
have these this long or a positive
negative this row isn't positive until
you make it positive so right now
nothing's attached to this row so it's
not currently positive but this is where
you'd want to plug in a wire from the
positive terminal of the battery okay
now one thing you might notice I hover
my mouse over here is that the whole row
highlights green and that's just a
signify that something plugged in here
is connected to something plugged in
there which is connected to something
plugged in there which is active
something we plugged in there and
they're in there and there so the whole
row is connected together same thing
with the negative row right there these
two are called the
rales just I think because it goes all
the way along the line now we look at
the inside components these are a little
different okay so it doesn't go right
across the row it's more the column so
we knows that it's one two three four
five so these five holes are connected
so something plugged into here is
connected to something plugged in there
it's not just there and so on okay so
one thing it with bread boarding and I
know we're using a this is a simulation
in the simulation you can plug in you
know I keep plugging a wire like that I
could plug in another wire like that in
real life you wouldn't do that you just
plug in one wire free to the holes and
I'll show you why in a bit okay so what
I want to do here I'll just delete
delete these components here delete
delete delete some of the wires I want
to take this battery I'm gonna rotate it
bring it over here and I want to connect
it up so let's take a look so I'll take
the positive terminal I'll click I'll
click on that there and so now this
whole row is positive I'm gonna take
that negative side plug it in there and
I'm gonna change the color of the wire
just so I know what that wire does right
and another good practice with red
boarding is is to connect from one rail
all the way to the other well I'll make
that black again I can go across like
this I could also bend my wire like this
but just by clicking and again I can
click here get red cross over just like
that and the good practice with that is
that now that stop rail is powered up
okay otherwise it won't be thought about
okay cool so now what I want to do I'm
gonna grab my LED and I'm just gonna
shove it in to one of these holes maybe
bring it over at this side yeah and I'm
gonna take my resistor and I'll bring it
right here awesome
and again the resistor so you could you
could do it on the side that comes from
the positive or I could do it the other
side going
from the negative doesn't really matter
so what I want to do oh no I want to
power this led up so I'm gonna grab I'm
gonna click right here and I'll click
right here so notice how okay I have a
positive terminal going wire going to
this rail it connects to this wire right
they're all connected which goes up here
and since it's plugged into this hole
this is connected to the resistor the
resistor goes across and is plugged into
this hole which is connected to the led
the positive side data led me now goes
through the lectricity will go through
the led to this side and now what I want
to do I need to go from the led to the
negative terminal because every circuit
I need to go from goes from positive and
goes through all the different
components goes to negative in order to
be completed and I'll press number one
and look at black I'll click right there
and let's see if this works and it does
okay so again we have electricity coming
from the battery positive terminal it
connects from this wire goes all the way
across and then it hits this wire here
delta T will flow through that wire to
this poor portion of the breadboard it
travels up here to the resistor goes
across the resistor and up to the LED
through the LED turns it on and it will
go all the way down to this negative
wire or the black wire here which
connects it to the negative terminal to
completed circuit so if any of these
wires here are deleted so if I delete
this wire right here
it breaks the connection and the LED
turns off so you need to have a
completed loop or positive to negative
okay so in this video we just briefly
looked at how to add some basic
components we made a basic circuit using
an LED a resistor a power source and we
looked at bread boarding and how we can
use a breadboard in order to connect
different components and this is
especially important in real life
where we want we don't want to solder we
don't want to permanently connect
different components we want to be able
to plug some in and remove them in so on
so thanks for watching this video like
and subscribe and I'll be making some
future videos
looking at programming Arduino and all
that sort of fun stuff okay take care
