Some pictures of a neopixel taken with my USB Microscope
What is a NeoPixel:
A NeoPixel is a small color led light with 4 connections.
Two points need to be connected to the power ( plus and minus ) One other connection is for an input control signal and the fourth connection may be used as output to connect to the next NeoPixel.
This way a lot con NeoPixels can be connected like a chain. The photos in this post are from a set of pre-soldered neopixels on a pcb where you can break out a small round pcb with one neopixel and the connections. This round led pixels can be used together with a micro controller (arduino, esp, .. ) in projects.

The first input needs to be connected to a micro controller. The micro controller can send send a signal and control each individual led separate to set the color and brightness.![](https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgwPt0sbhgL0A2vQzt-IQ7T-989holO2BKfla7bKxJJ2dx5wFWZYiT_LWEw2sOfKUjTAj9d8b3CXkQ5Dzp5a0zu-ojb31LIwSYEdvPkU8Qg63-RVfT_WtdJ8KFgFtsmug5PuMjRPQEMJ8YN/w200-h150/S20200311_neo3.jpg)
