However, it doesn't (IIRC) work with Megas.
True it does not work with Arduino Mega (and most of it's clones) but will work with the Seeeduino Mega
1112  Using Arduino / Project Guidance / Re: Trying my hardest to understand this. on: June 21, 2013, 01:22:53 am
One other thing, this is the code i'm using now and i've noticed that the LED will not turn off after the iteration is over.  Why not?
Code:
if (thisNote<=99){
should be
Code:
if (thisNote<99){
thisNote value goes from 0 to 99 then drops out of the for loop but your checking if it's 'less than or equal to 99' (that it always is). Changing to check 'less than 99' means your last pass through the for loop (thisNote = 99) will turn the LED off.

Yes but it dosn't take a web cam as an input. It is the sort of board I was talking about.
Well the OP does say

I would be using an IR capable web cam or some such sensor
so assumed the video source was not set in stone.

Something like this maybe. Not sure how easy it is to interface to arduino though.
1116  Using Arduino / Programming Questions / Re: How to make a sensor working once only when arduino is restarted? on: June 20, 2013, 05:16:54 am
Can you just put the code in setup() as it only gets run once per arduino restart and leave loop() empty?

I would assume (maybe wrongly) it's some form of cookie expired problem but AFAIK NoScript & AdBlock don't effect them. I do have 'Accept 3rd-party cookies' turned off and 'Delete all cookies on firefox close' selected. This problem also effects PC at work and home.

Which browser are you using?
Firefox v21.0

Have you seen these things http://lowpowerlab.com/blog/2012/12/20/moteino-the-wireless-low-power-low-cost-arduino-clone/ an 3.3V arduino clone with built in RF.
As to detecting other fireflies you could use IR to maintain the line of site principle but you don't need to try and decode the visible light flashes. Just flash the normal LED's as you see fit but also send a standard/custom IR code with the IR LED just after/during the flash sequence that can be picked up with IRemote on other fireflies.
1120  Using Arduino / Project Guidance / Re: How is this idea to measure a (tiny) gap? on: June 18, 2013, 10:04:57 am
You can get versions of this calliper that have computer outputs that you may be able to connect to an arduino. Then you could maybe put some form of expansion spring between the external jaws of the callipers to hold them open while the internal jaws are measuring the gap. As the gap closes the spring compresses and as the gap open the spring pushes the callipers open to fit the gap. Maybe a spring is not ideal as the weigh will increase as the gap narrows but you get the idea.

Why is it I sometimes get logged out of the arduino forum when I open a new browser tab to the arduino.cc site?
Many a time I have been in the process of composing a reply to someone on here and just visit the main site to get a URL reference only to find I have been logged out of the forum and my partially composed reply has been lost.  smiley-mad

To keep it arduino like you could maybe use a smaller chip like the ATtiny85.

Yes there is using AT command 'AT+PINxxxx' where xxxx is the new pin
1124  Using Arduino / Project Guidance / Re: 360 degree motion detector on: June 18, 2013, 02:17:47 am
I'm working on a project using an ILX511 CCD chip and using an MEGA or UNO I can analogue read in about 18uS but with overheads of storing results and driving clocks signals etc I take about 24uS per sample. This is almost flat out as fast as I can get. I sample the entire array (every other pixel on UNO due to lack of RAM) then pump the results out over serial for processing.
1125  Using Arduino / Project Guidance / Re: Using arduino to cool water on: June 17, 2013, 06:11:16 am
Sorry, more questions.
What temperatures are expecting to heat/cool the liquid to/from.
How fast do you expect to heat/cool the body of liquid.
Is it a closed or open system.
Does it need to be self contained or will it be able to use external resources.
