jiyuhan / iphone-position-tracker

This project can turn your phone into a gyro controller! I don't have the code for the iPhone side application, and I don't own the code for the microcontroller.

phoneController - part I

This is the project that I will be presenting on August 30th for club fair. A testing video can be seen here.

abstract

This project is simply using ATmega32u4 and a bluetooth LE (BLE) moduleto receive information from iPhone's gyroscope for the quaternion. Then, using serial connection to feed Node.js to create a server that updates iPhone's position. A client side app will use the data to control a webGL cube.

how does it work?

This project goes around like this:

iPhone (quaternion data)

⬇️ Bluetooth Low Energy (BLE)

Adafruit 32u4 Feather

⬇️ Serial Comm. (baud rate: 115200)

Node.js server

⬇️ parsed nicely and upload to http://localhost:8000/ (127.0.0.1:8000)

intranet

⬇️ taken by client side, and taken by 3D model

client virtual phone moves.

how to use it

First step is to start the server side. Run

ls /dev/tty.*

to determine which serial port you are using for Adafruit 32u3 Feather. Then change accordingly in serialToNode.js.

Then install dependencies. Type

npm install serialport

If it fails, try this

sudo npm install serialport --unsafe-perm --build-from-source

If still doesn't work, reading this might help.

Next step, install ws (websocket).

npm install ws

this usually should work fine.

After all this, open a terminal and run

nodejs serialToNode.js

Or if your laptop runs MacOS or maybe older version of node.js, try

node serialToNode.js

Next, we are to open the client side. Open the file index.html should do the job. It might not be able to support all the browsers, but FireFox should work.

web design

I previously had a temeprary website I designed, but now I have a better one there.
