Raspberry Pi
raspberry pi model b
The Raspberry Pi is
on the opposite end – it features a fully fledged operating system loaded on an
SD card. It also has audio out, HDMI and RCA video output and an Ethernet port.
This allows you to use your Raspberry Pi as a computer, complete with internet
browsing, games and more. Plug in your keyboard, mouse and monitor, and you
have an amazingly cheap computer.
The
Raspberry Pi projects are more software based than hardware based. As it is
simply a Linux computer, most projects are based around software hacks, media
centres and graphics/sound and multimedia. It can however do some simple
hardware control with the GPIO pins.
Arduino
the arduino uno
The Arduino is a programmable microcontroller. The only
functionality is what you program it to have. It is designed to read data from
sensors, compute the data, and either send the data to a PC (or raspberry Pi),
or output them to LEDs or LCD screens you have attached and programmed. By
controlling relays, you can control high powered components via relays and
control motors.
The
Arduino is used is many different types of projects, from musical applications
and interactive art exhibitions, to robotics and gaming gadgets. There are
quite a few different types of boards for different projects.
