Connect or Not: Pavilhao CIVIL, IST, Lisbon, September 2014

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

development

• 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, 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 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)

• Arduino ShiftPWM library
• Arduino diskoLEDron.ino firmware for LED control
• Arduino Arduino-Python 4-Axis Servo Control firmware for motors control
• python script, get-values.py interfacitng the incomiong values with systems reaction
• python libraries servoclass.py and ledclass.py; put them in the same folder with the main .py file and verify USB addresses before running

phone side:

• download and install 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 library,diskoLEDron.ino, Arduino-Python 4-Axis Servo Control, get-values.py, servoclass.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

python get-values.py

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

get the database file from the server;

read it using *sqlitebrowser*
