iPhone Integration

2009-03-24T14:49:00.001-07:00

I've finally enabled the javascript code to work for retrieving the Pachube feeds. Now my iPhone app is able to listen to the input from the Arduino, which currently still has 3 photovoltaics. Using the .json feed instead of the .xml (which i tried arduously to get to work with no success), i am able to implement the data with XMLHttpRequest.

Pachube to Web

2009-02-25T12:08:00.000-08:00

I now have my pachube feed displaying on the web. Next, I need to figure out how to make this displayable in an iPhone browser (no java support).

I just set up a Twitter account to try out remotely setting values for my Pachube feed. I wanted to test this as a possible application for use in the eventual iPhone application. Perhaps it would be useful to "tweet" the user inputs.

Pachube Input

Using a manual feed workaround, I am now able to push my data to Pachube. However, my digital switches are not registering properly, so only the right and left sensors are recording data.

System Diagram

In collaboration with my Visualizing [DATA] course, I setup a processing script to simulate a remote 'random walker' to use as a data generator. The presentation describes the structure of Brownian motion, as well as diagrams its use and my overall scheme.

Arduino to Processing (with Firmata)

Using the firmata library in the Arduino environment, I was able to control the microcontroller from within Processing with some minor alterations to the original code.

Simple iPhone app to get up and running using Xcode. It verifies left and right button taps.

Arduino 02

Initial setup with 4 inputs: 1 toggle, 1 push button, 2 photovoltaics.

The first run generated ASCII values (all of which are very difficult to see in the video) in the 700s, separated by commas, followed by two 0/1 outputs from the switches.

The second converts to binary.

*The ASCII values should be in the 200-300 range, but given that this setup is sensing light, the values change based on the environment, however I believe there are some wiring issues as well. So when converted to binary, the characters are not typical alphabetical letters.
