Can all things done on Arduino be done instead on a PI3 ?

[propergol]

Sorry if this question sounds stupid to some but when I see a youtube video for example demonstrating something done on an Arduino, can it allways been done also on a Raspberry?

Or may Arduino has specific hardware?

Thanks

No, everything cannot be done.

Arduino: 8 bit microcontroller, with analog inputs

Pi: 32/64 bit SOC, with Linux, graphics etc, but no analog inputs

VERY different beast.

Well, thanks for this clarification.

What has confused me is that I have seen some projects that was running on both ie: ntp gps based server, Hyperion (Ambilight) if I recall well.

So for example if I want to try to use the hardware of an existing cheap motorized IP camera (I have absolutely no clue if it is doable or not...) and control with some software, then Arduino is best suited hardware?

Basically, except for the simplest projects (ie blink an LED) you will have to modify the code.

Arduino has a LOT of pre-written libraries.

The vast majority of those are not available on the Pi, so you would have to write the equivalent functions.

It is pretty easy to add an analog to digital converter, what will be difficult for you is interfacing some random sensor, for which there is already a library for the Arduino, but not the Raspberry Pi, to the Pi.

If for every sensor you consider buying you first google for a Raspberry Pi example, you can do OK.

If you buy a random sensor/part that has some Arduino code, you will likely be out of luck.

See Gordon's http://wiringpi.com/ for some Arduino compatible libraries for the Pi.
