You may have been asking yourself the question what is a quantum dot?

After all, the buzz surrounding quantum dots — especially in the TV and display industry — is loud right now.

And while this post is about what a quantum dot is and how they work and not about TV displays, television is something we’re all familiar with and most of us own at least one. This gives us a convenient and familiar way to explain some of the concepts behind them and answer the question: what is a quantum dot?

Toward that end, if you’re looking for a write up of various display technologies or recommendations on which TV to buy, sorry, this is not for you.

If you’re looking for information on quantum dots and want to learn more about them, this is for you.

A while ago, I wrote an article called A Closer Look Inside the Arduino Uno. In the article, I glossed over powering the Arduino.

The post also gives a brief history lesson on the board, goes over the layout and some of the main components, discusses the Arduino pin out, and finally, talks about a few nuances of the Arduino Uno which may cause some seemingly weird errors to occur.

In that post, I made the promise to go into more detail on some of the often overlooked, but important nuances of the Uno.

This time around, we’ll delve a bit deeper into powering the Arduino Uno and talk about some of its limitations and best practices for doing so.

Let’s get started!
