Configuration

• Raspberry Pi 3
  • Raspbian GNU/Linux 8 (jessie)
  • Nginx (1.6.2)
  • uWSGI (2.0.14)
  • Python 3 (3.4.2)
  • Homebridge (Optional)
• Arduino Uno

API

GET

• /led/on: Turn red LED on.
• /led/off: Turn red LED off.
• /led/blink/<count>: Blink red LED <count> times.
• /led/brightness/<brightness>: Change brightness of red LED.
• /indicator/on: Turn indicator LED on.
• /indicator/off: Turn indicator LED off.
• /indicator/blink/<count>: Blink indicator LED <count> times.
• /motor/on: Turn motor on.
• /motor/off: Turn motor off.
• /motor/speed/<speed>: Change motor speed. <value is a range between 0 and 100.
• /motor/cw: Rotate motor clockwise.
• /motor/ccw: Rotate motor counter-clockwise.
• /heartbeat/<bmp>: Change pulse of red LED. 0 to stop.
• /step/<steps>: Change rotation speed of motor. 0 to stop.

POST

• /automata: bpm=<int>&step=<int> Enter any positive integers to blink LED and rotate motor. Use bpm=0&step=0 to stop blinking LED and rotate motor.

Build

1. Connect to Raspberry Pi via SSH or open Terminal.

   • ssh pi@<address> or ssh -R 52698:localhost:52698 pi@<address> to use rsub.

2. Install dependencies.

   • sudo apt-get update
   • sudo apt-get upgrade
   • sudo apt-get install arduino
   • sudo apt-get install nginx python3 python3-dev python3-pip
   • sudo pip3 install uwsgi flask flask-restful
   • To install Hombridge, go to Wiki. (Optional)
     • curl -sL https://deb.nodesource.com/setup_6.x | sudo -E bash -
     • ``sudo apt-get install -y nodejs`
     • sudo apt-get install libavahi-compat-libdnssd-dev
     • sudo npm install -g --unsafe-perm homebridge hap-nodejs node-gyp
     • cd /usr/lib/node_modules/homebridge/
     • sudo npm install --unsafe-perm bignum
     • cd /usr/lib/node_modules/hap-nodejs/node_modules/mdns
     • sudo node-gyp BUILDTYPE=Release rebuild
     • npm install -g homebridge-http

3. Clone this repository to any directory.

   • git clone https://github.com/gbmksquare/Interaction-Design-Automata.git

4. Verify and upload /arduino/arduino.ino to Arduino Uno using Arduino IDE.

5. Run /python/home.py and test with a web browser or Apple HomeKit (if using Homebridge).

   • uwsgi --socket 0.0.0.0:8080 --enable-threads --protocol=http --ini home.ini

6. Make a symbolic link to Homebridge configuration file and run Homebridge. (Optional)

   • cd ~/.homebridge

• ln -s <path_to_project>/homebridge/config.json config.json
• homebridge
