Led lamp - Neopixel Ring 24 with Arduino Uno.

thingiverse

I've created a LED lamp controlled by an Arduino Uno, you can modify the code to change the light pattern. I've added a pattern that imitates a fire. You can search for tutorials online for using an arduinop with a neo pixel ring, it's pretty simple and you can find different light patterns.Hope you enjoy!
