Devices like Arduino Uno, Raspberry Pi and Beaglebone Black welcome IoT to change the world

Nowadays there are many credit sized computers which are aimed at IoT (Internet of Things) services: Beaglebone Black, Raspberry Pi and Arduino Uno, just to name some of them.

Why have these computers become so popular? There are many reasons:
  • They are cheap
    • Raspi costs ~ 30-50 euros depending where you buy it
  • They are open source
    • Try to find proprietary (= closed source) micro-controller as cheap as Arduino Uno
    • Open sourcing has taken the price down
  • GPIO (= General Purpose IO) pins
    • All sort of electronic hobbies are possible via these pins
  • They don't need a lot of room or power
    • Low energy devices are suitable for IoT
    • They can be driven remotely via for example SSH
World will be even more networked in the future. One step forward in that scene are devices like Beaglebone Black, Raspberry Pi and Arduino Uno which are platforms for all kind of first-generation Internet-of-Things -services.

Beaglebone Black is especially aimed at IoT

Raspberry Pi runs Raspbian Linux and works the
same way as Beaglebone Black

Arduino Uno is a micro-controller with no Linux 
inside but the program code directly in the memory instead

GPIO pins are those with wires attached
