HomeBright: Smart Home Lighting Control with Leap Motion & Arduino UNO

Apps and online services

Arduino IDE

About this project

This app uses LeapMotion and Arduino Uno to create a home automation system which controls the intensity of lighting of rooms. A home floor plan is mapped to the LeapMotion coordinates to determine a particular room. While palm position controls the lighting of a targeting room, raising or lowering the palm controls the intensity of lighting of the room. 

Instruction

Install node.js

Install Leap Motion SDK

Install Cylon.js for Arduino and Leap Motion (Refer to useful links below)

or use the package.json to install all the required node modules

How to Run

run:  node homebright-console.js (Refer to code section)
