hey kids have you ever wondered how
0:02
machines in big factories know exactly
0:04
what to do it's like they have a super
0:07
smart brain telling them what to do and
0:09
when to do it well guess what they do
0:13
have a special brain and it's called a
0:16
PLC let's discover the amazing world of
0:21
superheroes before plc's came along
0:24
controlling machines in factories was
0:26
super tricky imagine trying to play with
0:29
a huge comp licated toy that's hard to
0:31
change or fix That's What factories were
0:34
like but then a clever engineer named
0:37
dick moley had a brilliant idea in 1968
0:42
he created the first PLC it was like
0:45
giving factories a brand new super smart
0:48
toy to play with this new PLC was
0:51
amazing it could be easily programmed
0:54
just like when you're telling a story to
0:56
your toys Factory workers could quickly
0:58
change how machines worked without
1:00
having to rewire everything plc's made
1:04
factories much better in many ways they
1:06
were more reliable like a toy that never
1:09
breaks they were smaller so they didn't
1:11
take up as much space and best of all
1:14
they were flexible like being able to
1:16
change your Lego creation whenever you
1:18
want as time went on plc's got even
1:22
smarter and more powerful they helped
1:25
create the super cool Hightech factories
1:28
we have today it's like the factories
1:30
leveled up in a video game now plc's are
1:34
everywhere in the world of big machines
1:36
and factories they help make the toys
1:39
you play with the food you eat and even
1:41
the car your parents drive plc's are
1:45
like the hidden Heroes of the Machine
1:46
World wow we've learned so much about
1:49
plc's today remember how they're like
1:52
super smart brains for machines and
1:54
factories plc's made factories much
1:57
easier to control and change it's like
1:59
having a magic wand that can make
2:01
machines do exactly what we want and
2:04
thanks to plc's we have all sorts of
2:07
cool things in our lives from Toys to
2:09
cars to yummy food plc's help make our
2:13
world more amazing every day and that's
2:15
the amazing story of plc's the super
2:18
smart brains of machines isn't it cool
2:21
how one clever idea can change the whole
2:23
world remember next time you see a toy
2:26
or a car or even your favorite snack
2:29
think about the incredible plc's that
2:31
helped make them they're like the hidden
2:33
Heroes of our world thank you for
2:36
joining us on this exciting Journey
2:38
Through the world of plc's keep being
2:40
curious and who knows maybe one day
2:42
you'll invent something amazing that
2:44
changes the world too
