How to use Leap Motion create vectors

Introduction

In this tutorial, you will be able to use  Leap Motion sensor to create vectors. This tutorial shows capability to our “Wind [Motion] Chime” setup which is use Leap Motion to control the Wind Chime move up and down and make sounds.

Tutorial Parts List:

  • Arduino UNO (1)
  • Leap Motion (1)

Step 1

Go to website: https://www.leapmotion.com/setup?lang=en

3.0

Download “the Leap Motion Controller

Install Leap Motion Controller

 

Step 2

Go to website: http://www.onformative.com/lab/leapmotionp5/

1.0

Download library “LeapMotionP5 archive v0.5

Install the library

4.0

 

Step 3

Processing Code

Go to the “File” menu –> Examples drop down, you should be able to see the names of the new library that you’ve just installed. Find out “active_fingers”, and open up.

6.0

 

Copy the code

import com.onformative.leap.LeapMotionP5;

import com.leapmotion.leap.Finger;

to the very front of the new sketch

5.0.

In the “active_fingers” example, Leap Motion could sense 5 fingers’ movement and draw ellipse.

In the new processing code, we use Leap Motion to create vectors.

Here’s the Sketch for the example: active_finger:

 

Here’s the Sketch for the “Leap Motion Wave”:
