Did you read our explainer on display technologies? If so, you'll already be well aware of the concept of PPI, or "pixels per inch," which is a more informative measure of "display resolution" than a ...

I’ve seen a lot of Pixel LED projects and know every maker does things differently. I wanted to show you what I am doing for my Pixel LEDs. This post will give you an Arduino Pixel LED Controller ...

So you've already outgrown Arduino's most beginner-friendly board, the Uno, and are looking to move on to bigger, more exciting projects. In that case, the Nano family might just be what you need.

I have spent at least an hour almost every day since the 80’s advancing my knowledge in electronics. Recently I brushed up my knowledge on LED fading secrets and attained something pleasant. Now, I’d ...

How researchers are pursuing the manufacturability of arrays of micro-optical devices. How one team is roll-printing micro-LED arrays. How another team is growing nano-LEDs using perovskite materials.
