Interactive NeoPixels

In this project we'll build an LED Trampoline. This is a really fun project that lights up when you jump on it! These trampolines are meant for exercising and jumping on this thing for just a few minutes feels like a working out so perfect for tiring out kids, just be sure to supervise them. It works really well and looks amazing at night, especially around a fire pit with a fog machine.


I found this trampoline at my local Wal-Mart near the sporting goods isle. It was about $25. It has 6 detachable legs which is convenient for storing. It's meant for cardio workouts and features elastic straps instead of metal springs, which is pretty nice.

Reel of NeoPixel LEDs

The trampoline is about 36 inches in diameter, which is fairly large so I used a 3 meter long LED strip to wrap around the whole framing. There's a little bit extra here, about 10 pixels, but this should give us plenty of LEDs to work with. The Low density strip contains 30 LEDs per meter, giving us a total of 90 RBG LEDs. You can choose to use a medium/high density, but be aware there are hardware limitations in Circuit Python.
