    Pachube sensor client with Strings

    This sketch connects an analog sensor to Pachube (http://www.pachube.com)
    using a Wiznet Ethernet shield. You can use the Arduino Ethernet shield, or
    the Adafruit Ethernet shield, either one will work, as long as it’s got
    a Wiznet Ethernet module on board.

    This example has been updated to use version 2.0 of the Pachube.com API.
    To make it work, create a feed with two datastreams, and give them the IDs
    sensor1 and sensor2. Or change the code below to match your feed.

    This example uses the String library, which is part of the Arduino core from
    version 0019.


    • Analog sensor attached to analog in 0
    • Ethernet shield attached to pins 10, 11, 12, 13

    Domains and Ideas for Last Project.

    1.) Seriers of objects that comment on Internet of Things/ data gathering and analyzing…

    toilet bowl cleaner / toilet / etc that sends data to Pachube.

    2.) Interactive installation or game  that deals with multi- cultural experiences/confusion

    3.) Performance dealing with coming of age rituals -> specifically ones dealing with altering the body

    4.) crossing borders ( Installation about trials of border crossing )

    5.) Children loosing their mother tongue due to assimilation resulting in loss/change of identity                        ( installation)

      Hardest part of the exercise was coming up with idea/concepts for projects.I STILL CANNOT COME UP WITH CONCEPTS….I HAVE A TOTAL BRAIN CLOG. Easy parts were coming up with domains for areas of interest. I general areas of interest but am having issues coming up with a strong concept of any kind minus my Pachube sarcastic commentary.

    Heart Racer (The Game) 

    Heart Racer is a goal-based toy that tasks the user with learning how to control her own heart rate within a playful setting.  When the game begins, the player picks a card at random from a stack.  Each card has five circles, each set to either red or blue.  The player must control her heartbeat to recreate the card’s color pattern on the Heart Racer device’s five LEDs.  The player has ten seconds to affect each LED; a low heart rate turns the LED blue while a fast heart rate turns it red.

    Friends with multiple Heart Racer devices can also compete by using the same card.  The user whose Heart Racer most closely matches the pattern on the card wins that round.

    Heart Racer uses the Pulse Sensor to take the user’s heartbeat.  It also uses 5 Red-Green-Blue LEDs to show the user her current heart rate.  Finally, it uses an Arduino as the microcontroller that brings all the parts of the project together.

    Amira and Ramiro’s Midterm Journal 2 Entry 

    pictures above in order: 1. physical prototype 2. Code( next phase ) 3. Cards ( look and feel )to indicate patterns players should attempt to mimic using their BMP


    In 4-8 sentences, Describe what how you will work on your prototypes between now in next class.  What is left to do?  What surprised you?

    Between now and next class Ramiro and I will

    1.) Implement and refine final physical protoype. —We will make 2 controllers so that there is the option to play against another person as well as yourself.

    2.) Transfer our paper version patterns to actual cardstock — we will make a complete deck of patterns for our players to compete.

    3.) Refine our code

    Our materials to house our final version/hardware has been ordered and we await its arrival. We will be using a wooden casing to house our Arduino because of the look and feel it provides.( Also our metal version is conductive and interferes with the hardware.

    Amira Anne Pettus MIDTERM_ Journal Entry 1 

    Project overview:

    Originally a screen based game that allowed the player to manipulate their BPM in order to complete a time color matching game against a set pattern created by the computer.( BPM ranges matched up to specific colors which the player must discover and manipulate to match the computer’s color based patter.)

    Physical Object: The game became physical and now the player has a handheld object embedded with RGB leds. The concept is the same,however instead of squares on the screen the colors of leds are changed depending on BPMs.

    known and unknown challenge :

    To make a game ,using the heart sensor, that one could play alone or with another person. There was some initial trouble with mapping the BPM to the color ranges as well as creating a range that the player could manipulate to change the colors of the boxes(LEDs).


    surprising: How the project evolved from living on the screen to a physical object and the natural handheld shape it took on.

    jewel/wildcard: When the project was screen based and the players competed against each other to match the computer generated pattern we had trouble thinking about how to make this aspect physical. The idea of cards with pattens came up and I believed fit in with the feel of the game nicely.

    Assignment 1 Moody “Cube” 

    • Amira Pettus 11:20 pm on February 16, 2012 Permalink | Reply

      1.What was surprising about making your project?

      Instead you using multiple separate LEDS I used a single RGB LED, I assumed that the methods for fading and flashing would be almost identical to single LEDS and I was mistaken. I learned that different colors are activated and are visible in different amount and trying to arrive at a single suitable color combination proved to be interesting.I thought it would be simple to come up with switches for transitioning between “moods” but the potentiometer I used is quite finicky. Instead of moving smoothly between each mood it is hard to determine how to be in specific sections of fading,flashing A and flashing B.

    1st Post yeah! 

    1.) Amira Anne Pettus


    3.) I have a B.S. from Georgia Tech in Science,Technology,and Culture.

    4. I wanted to be in this class because I need to acquire practical skills that I can apply in the job market. I also would like to learn technical abilities so that I am able make physical objects/pieces.
