The APA102 chip uses PWM rates of 19.2Khz which allows DotStar LEDs to be used in Persistence of Vision (POV) displays and smoother PWM fading. However instead of only requiring a single pin to transfer data, the DotStar LEDs require two, so let’s take a look at how to use them.

Floating and Spinning Earth Globe

“The objectives of this project were (1) to make an object float, by means of magnetic levitation and controlled by an Arduino Nano and (2) documenting the whole process allowing other people to build one on their own. There were …

“This project consists of a 3d printed persistence of vision (POV) globe which is able to render arbitrary spherical images from appliations, written in c++ or python.”

Persistence of Vision Christmas Ornament

“As you can tell from my list of instructables, each year I try to come up with a new and interesting Electronic Christmas Ornament. They are usually loud, heavy, and something generally too big for the average tree, with that …

Persistence of Vision LED Staff

“It is well known that even after a light has been turned off, human eye keeps “seeing” it for a fraction of second. This is known as Persistence of Vision, or POV, and it allows one to “paint” pictures by …

Make Your Own POV LED Globe

“In this project I will show you how I combined a couple steel pieces with an Arduino, an APA102 LED Strip and a Hall effect sensor in order to create a POV (persistence of vision) RGB LED Globe. WIth it …

POV Bike Display - ESP8266 + APA102

“How to turn your bike into a moveable screen in the city? This instructables aims to answer how to do that cheap and easy with parts most makers already have lying around. Before we start on how to build the …
