Jump Sensitive Neopixel Trampoline

In this instructable, I will show you how to build a trampoline that changes colors whenever you jump on it!

Step 1: The Things You Need



  • Soldering iron
  • Hot glue gun – To insulate and protect the wiring
  • Wire strippers
  • Wire cutters
  • Scissors

Step 2: Assemble the Trampoline

The box has the instructions, they are pretty straightforward.

Don’t touch the electronics, we will use it later πŸ˜‰

Step 3: Cut the Neopixel Strip

There are exactly 30 spaces between the bands that hold the jumping cloth in the trampoline. We will cut the the Neopixel strip into 30 individual LEDs, and put them between each band.

Note: There are spots that have solder holding the strip together, you can easily cut them too.

Step 4: Soldering the LEDs

  1. Cut each wire to about 2.5 inches. This will make sure that the wire connections between LEDs are longer than all of the band lengths
  2. Strip the wires on each side
  3. Solder the wires to the LEDs. Leave the protective plastic to protect the LEDs
  4. Do this about 10 LEDs at a time (see the next three steps)

Step 5: Hot Glue All of the Connections

Step 6: Check That Everything Is Working So Far

Connect the strip to the Arduino in the following order.

  1. Connect the ground, MAKE SURE YOU CONNECT THE GROUND PINS FIRST. The LEDs are very fragile
  2. Connect the other two pins. Make sure the Din pin is a PWM pin. (Look at the diagram)
  3. Download the Fastled library here, and import it into your arduino IDE
  4. Go to my git repo and download check_leds code (https://github.com/seniorburito/led_trampoline)

This code will lit LEDs in order, so if there is a problem, you will see which one needs fixing.

Also make sure to read the Fastled documentation here, it is really well-written

For now, you can put arduino on the side, or under the trampoline.

Step 7: Attach the LEDs to the Trampoline With Zip-ties

I tied each led with two zip-ties to prevent leds from moving. Zipties might work better because you can take them off if you decide to take off the LEDs and because zipties are cheap.

Step 8: Hack the Jumping Sensor

The trampoline comes with a device that counts calories based on how much you jump. We cant do anything with the chip,

but if you open up the jumping sensor, you will realize that its just a toggle switch that triggers on when you apply force on it. It is very easy to use toggle switches with Arduinos. Therefore, we will use it in this project to sense jumps, and trigger effects when that happens.
