Upgrade your trampoline by adding interactive LEDs

Adafruit Industries has created a tutorial to upgrade an ordinary trampoline by adding fun, interactive NeoPixel LEDs.

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.

Yes, please!
