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
- Origami Paper (or printer paper cut into a square)
- Wire Stripper
- 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 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.
