What Is Arduino? What Can You Do With It? Explained

The Arduino is a remarkable device for electronics tinkering. Learn what it is, what you can do with it, and how to get started.

This is an update to our original "What is Arduino?" video, which has over two million views.

Thank you for this video. I've never worked with electronics in any capacity before, and you really nailed it in an understandable way.

Great video, thanks!

I work with Industrial PLCs for a living and primarily use Ladder Logic with very limited structured text and function block diagram in the programming. I was going to mention the micro/mili secont bit but saw someone already did. Cool to see it used here as it is the most common time base used in the PLCs that I've seen. I want to start picking up some DIY projects and learn a bit more of textual programming language. Thank you for the vid and recommendation on the starter board. I want to see what functions I am able to mimic from ladder logic and for my first real project I want to make an automatic pet feeder for 2 cats ! 😄 Thanks again!

I think he might be misusing the term microsecond. There are 1, 000, 000 microseconds per second. There are 1, 000 milliseconds per second.

I've been using mine with an lcd key shield to code in security keys for game boards but just lately been wondering what else i could use it for, its a great bit of kit.

As a fan of JavaScript, Solid.js and Node.js - coming to Arduino - I really hate the semicolons in C++. I think I need to install MicroPython.

nice one, but u might to give it a replay to get it a little bit more clear

The time is in milliseconds, micro means "1 millionth".

Ardrino hardware make a stereo music system

How is this compared to the raspberry pi?

[George-ntuw]

Milli-seconds, not micro-seconds in delay

In typical nerd fashion, some insanely complex topics are brushed over as if "everybody knows that." The programming code and syntax are utterly incomprehensible. He makes no mention of where to find and learn that code. Ardiuno cannot be used without knowing that secret coder language, so, in a sense, this video is useless.
