Handling exceptions in processing

What if an arduino is not connected? Or some code issues? Great post on handling exceptions in processing.

Firmata link between processing and arduino

The simplest way to get processing and the arduino to talk is by loading the
standardFirmata sketch onto the arduino. This recognizes whether pins are inputs or outputs based on the processing code.

Then on processing I am using a simple code to display data
firmataReadAnalogMultipleandDigital.pde which reads analog pins and a digital pin

Firmata link between processing and arduino

Now running a sketch in processing that reads the values of 3 sensors, actually potentiometers for testing. Displays values as bars in processing, and the circle is colored RGB by these values.

Firmata and contro of arduino from PC

Good explanation of firmata using processing and also here, and then the version for Visual Basic

Serial out

Tigoe has excellent tutorial on serial out, and read into processing.  A must do!


and an awesome serial out to processing and radar screen.  Should work for Hospital monitor!

Programming arduino wirelessly using Xbee

Faludi wrote a beautiful tutorial on using XBees to program arduinos, and a wireless connection to the internet using xbee.

Upgraded Xbee - processing screen

conductive thread, ink, fabrics

I could paint with silver impregnated paint ot create circuits, or make paints as shown in this instructables, and there are even pens, and conductive thread out there........ endless possibilities as shown by the great work of Leah Buechley who also has a great links page.

processing and mapping coordinates

To map coordinates on any images, I wrote a processing sketch to display x and y coordinates as a rollover.  Can use this to determine sizes and areas of coral species.

processing

before I forget about an incredible exhibit at MOMA, called Design and the Elastic Mind.  Lots of uses of processing language and some great processing of geographic data

new book arrived

Physical Computing by Dan O'Sullivan and Tom Igoe arrived.  Tom Igoe has some amazing work on the web and his students at NYU  have pushed physical computing to some amazing heights.  Should give me a lot to think about with microcontrollers and linking them to computers
