![]() ![]() The design is also fairly modular, so you can make it as big or small as you like. But there are a lot of useful techniques and components that you could use for other kinds of projects. Now, I'm not going to lie to you: this project is a lot of work, and some of it is pretty tedious. Check out some of the examples in the videos above. This data is fed into a microcontroller that lights up the NeoPixels in interesting patterns. The table consists of a large array of infrared emitters and sensors, which are used to detect the rough location of objects on or above the table. Welcome to my version of the LED reactive table! I was inspired by previous work using discrete LEDs, such as this one, but I figured it would be easier and more fun to use NeoPixels - programmable RGB LEDs that can be set to any color you want.
