# PiPHL
Haptic Passive Learning of Morse for the Raspberry Pi


# Objectives

This project aims to assist with learning morse code via a raspberryPi with a haptic motor and some headphones. Using techniques from the Haptic Passive Learning experiments run by the Georgia Institue of Technology.  [Their Paper](http://dl.acm.org/citation.cfm?id=2971768)


# Dependancies:

Adafruit GPIO libraries and PyAudio

```apt-get install python-pyaudio adafruit-gpio```


# TODO

- [X] talk to motor controller
- [X] record/find audio
- [X] document hardware choices
- [X] python library for motor controller
- [X] python async audio playing
- [X] generate sequences on the fly

# Hardware
