5/Arduino and the Pi
As you’ll see in the next few chapters, you
can use the GPIO pins on the Raspberry Pi
to connect to sensors or things like blinking
LEDs and motors. And if you have experi-
ence using the Arduino microcontroller de-
velopment platform, you can also use that
alongside the Raspberry Pi.
When the Raspberry Pi was first announced,
a lot of people asked if it was an Arduino kill-
er. For about the same price, the Pi provides
much more processing power, so why use
an Arduino when you have a Pi? It turns out
the two platforms are actually complemen-
tary, and the Raspberry Pi makes a great
host for the Arduino. There are quite a few
situations where you might want to put the
Arduino and Pi together:
• To use the large number ...
