===== technical details =====

Stretchable fabric + motors + custom designed LED RGBW boards + 2 Arduinos + laptop + Connect or Not Android app 

[[connectornot-lisbon-development|development]]
==== hardware ====

  * stretchable fabric, 2.25x7m
  * 2 wooden bars, 5x5cm, 2.25m long
  * 2 wire cables, 7m long
  * hooks, screws, staples…

  * Arduino Uno board
  * Arduino Mega(ATMEGA1280) board
  * custom made shield with connectors for the motors and independent power
  * 24W Universal AC Power Adapter, on 6v

  * 4 HiTEC ultra torque servo motors, [[http://www.servocity.com/html/hs-645mg_ultra_torque.html|HS-645MG]]
  * modified the servos for continuous rotation, using this procedure [[servo-continuous-modify]]
  * plexiglass wheels on motors

  * 4 custom made RGBW LED light boards

  * 3 [[http://estimote.com|estimote beacons]]

  * laptop (Debian Wheezy) with built in wireless adapter Intel® Centrino® Advanced-N 6205 with Intel(R) Wireless WiFi driver for Linux, 3.11-2-amd64 (iwlwifi)
  * smartphone (tested with Samsung Galaxy S3, Android 4.0.4)

==== software ====

  * Arduino [[shiftpwm-led-controls|ShiftPWM library]]
  * Arduino [[diskoLEDron-ino|diskoLEDron.ino]] firmware for LED control
  * Arduino [[multiple-serial-servo-control|Arduino-Python 4-Axis Servo Control]] firmware for motors control
  * python script, [[connectornot-lisbon-py|get-values.py]] interfacitng the incomiong values with systems reaction
  * python libraries [[servoclass-py|servoclass.py]] and [[ledclass-py|ledclass.py]]; put them in the same folder with the main .py file and verify USB addresses before running


===== HOWTO =====

phone side:

  * download and install [[https://play.google.com/store/apps/details?id=net.lmag.connectornot|Connect or Not app from Google Playstore]]
  * press the PLAY button to start counting and sending data

laptop/beaglebone side:

  * download all necessary scripts and libraries [[shiftpwm-led-controls|ShiftPWM library]],[[diskoLEDron-ino|diskoLEDron.ino]], [[multiple-serial-servo-control|Arduino-Python 4-Axis Servo Control]], [[connectornot-lisbon-py|get-values.py]], [[servoclass-py|servoclass.py]], [[ledclass-py|ledclass.py]]; put them in the same folder with the main .py file
  * connect both arduinos to the laptop, verify USB addresses before running
  * optionally, you can write udev rules for your machine so that the naming of USB serial addresses is persistent http://hintshop.ludvig.co.nz/show/persistent-names-usb-serial-devices/ or  http://hackaday.com/2009/09/18/how-to-write-udev-rules/
  * start get-values.py
<code bash>python get-values.py</code>

browse, talk, send sms's and upload data over the network. observe changes in the movement and lights

==== HOWTO analyse position tracking ====
