Pachube: Someone has a great idea here. Set up a website mashup of a lot of peoples remote sensor data. Can even control your arduino from their website, kewl. They have a section with code dedicated to the Arduino. It's in beta, and I have in an application. Soon you too can see how cold it is down in my shop.
This looks very promising. A way to burn a bootloader (or any code I guess) into a blank mega168chip. using the BitBang mode of the USB chip and a slightly modified version of the AVR jtag program. I just HAVE to try this. [link]
Yes Virginia, you can have a webserver in 14K of memory (that's K as in thousand not gig or meg)
I couldn't find any example code for making a web server with the Arduino 12 IDE - so I knuckled down and struggled through writing my own, and learned a LOT in the meantime. This example displays all the analog pin's values, and lets you set the Digital output pins on or off. Its HTML web code so it is necessarily messy. There are comments, such that they are, to try and shed some light on the process.
The Wiznet can deal with more than one connection, so I had to make sure that any new page got what the current digital pins values. But had to sacrifice the ability to turn all the pins off.
HTML is a bite, and to truly do something that would be useful it would need a telnet connection so we could get some dedicated two way communication - and or a little AJAX code in the browser page to update things in real time.... That is for another day.
If you change the code - make it more useful - do me a favor and drop me a line letting me know. I'll practice now heaping praise - ohhh awwww - fantastic!!!!
