All You Need To Know Raspberry Pi
Let’s talk about raspberry pies cornerstone of the tinkering community and
despite their deliciously deceiving name raspberry pies aren't for a tasty
treat they're for computing and programming my friends that's the tasty treat
but please don't even hear some programmers they could get stuck in your teeth.
Raspberry pies are teeny tiny super cheap computers with the largest being
about the size of a deck of cards and the smallest being slightly larger than a
stick of gum.
Well that's incredible will you say but that don't look like any computer
I've ever seen
You say again all right let's be real this thing looks like if Quasimodo
and Tyrion Lannister's somehow had a baby how can this thing be a full
computer.but despite what it looks like it has everything a normal-looking
computer has.
Look it's got everything you need to connect a monitor keyboard mouse the
Internet heavens to Betsy folks we got ourselves a full-fledged computer.
One setback here though is the most popular computers on the market run
Windows or Mac operating systems but the Raspberry Pi runs something called
Linux as their desktop operating system.
to be specific it's a version of Linux called a raspbian designed
specifically for the Raspberry Pi.but not all pies are created equal there's
several different versions and to find out which one is right for you let's give
the family a rundown.
Roll call introducing the PI zero this is the run to the bunch it's super
tiny it requires a few extra adapters to get everything connected to it but
once you do it's great for projects that have very little extra space and while
it's the cheapest of the bunch $10 with y5 $5 without it also doesn't have as
much computing power as compared to its bigger siblings.
All right it has a faster processor than the PI zero but the
same amount of memory a full-sized USB port audio port and a
full-sized HDMI port the newest versions even have built-in wireless and
Bluetooth and this one is gonna set you back about twenty-five dollars and here
we have the model B's series the older wiser PI with all the bells and whistles
yes this PI can knit a Hogwarts sweater while saving a cat from a tree it can
recite the Canterbury Tales while rebuilding an engine it has four USB ports a
full-sized Ethernet jack and up to four gigabytes of memory quad-core processor
and the newest versions even support dual monitors that's more power than a lot
of laptops have on the market.
Now don't expect to be playing for at night on this thing but starting at
$35 it's one of the cheapest decently powered computers on the market alright
so having a cheap full fledged computer is cool but let's address the real
reason this PI has become so popular.
This little pincushion right here these things are called general purpose
input output pins or GPIO pins for those of you guys that don't like long words
these pins can sit and receive electrical signals and you can control those
electrical signals from the operating system.
Okay before we start wandering too far to nerd topia here what's that mean
for the uninitiated
Okay being able to control electrical signals means that you can control a
lot of things that use electricity to run so starting out small for example
that'd be things like LED lights motors buttons switches radio signals audio
signals and even LCD displays.
Just to name a few you could make a display that shows your YouTube subscribers
you could even add joysticks and buttons to make your own mini arcade system
it's actually pretty limitless what you can do with these GPIO and it
takes the Raspberry Pi from the computing world to the physical world.
That's as refreshing as having a campsite with a bidet if you've ever been
curious about electronics or programming then the Raspberry Pi is an excellent
tool to have in your arsenal and at five to thirty five dollars there's not
much of an excuse not to have one so if you didn't know about raspberry PI's
before and now you know and you're one step closer to being the master tinkerer
that you're destined to be if you made it this far congratulations here's your
reward did you know that one of the first computer science PhDs was earned by a
nun.
