Proximity Sensing Origami Flower

Contest Winner

Origami is the traditional Japanese art of paper folding.  In this project, with a little help from an Arduino, you can bring your origami into the 21st century and make it an interactive art!

The result shown here uses Bare Conductive paint to give an origami flower proximity sensing powers.  When you put your hand close by, it triggers a small vibrating motor, and the flower wiggles around to say "hello!".

Step 1: Tools & Materials

Picture of Tools & Materials
Let's get started by gathering the necessary materials:
  • Origami Paper (or printer paper cut into a square)
  • Wire Stripper
  • Pliers
  • Scissors
  • Paper clip
  • copper wire
  • electronics prototyping breadboard
  • arduino board and arduino sketch software
  • Capacitive Sensing arduino library (from here)
  • small vibrating motor as from a cell phone battery
  • Several 10M Ohm resistors
  • Bare Conductive paint
  • paint brush
  • computer for loading code onto Arduino (not shown)
  • Attached Arduino sketch (rename from ProxFlower.ino.txt to ProxFlower.ino)
  • OPTIONAL: for more flower flair, add connect an LED in addition or instead of the motor
 

Step 2: Make and Prepare An Origami Flower

The first step is to make an origami flower or other origami/paper object to which you want to add proximity sensing powers.

The flower below was created by following the instructions presented at this link.  It is the traditional way to fold a Lily.

Once the flower is completed, cut off the bottom of the flower to make a place to thread the vibrating motor leads through.

Finally, paint the petals with conductive paint, making sure that the entire painted surface is continuous across the petals.  As I did this project, I painted the flower fairly late in the process and used a painted post-it note to test out the circuit first, so you will see the flower as unpainted through most of the Instructable.
