How would that be done?  Larry
2  Using Arduino / General Electronics / Need to measure -30c to 150c on: December 18, 2013, 11:51:50 am
Hello Forum, I am in need of some help with measuring very low temperatures.  The LM35 sensor has the range, but from +25c to -55c the output is in negative volts.  How do I deal with this problem.    Thanks for any help, Larry

Thank you Down-under, for taking the time to lend a hand.  I am looking into your idea.  I am looking for a sketch that I can use.  I have looked at the amplifier circuits, I think I could handle that.  I will post my results.

Thanks for you help, Larry

Thanks for the tip. I am looking into that now......Thanks again....LEE

Thanks for real good the suggestions.  I think you are right about duel systems.  I went to the goldmine site.  I am going to buy both of those items and see what I can work out.  Thanks again, I will keep your address and let you know how I do....LEE

Thanks for the suggestions.  Jane is not with it enough to push buttons.  Bed alarms don't work, if she only sits up, we tried those things.  I think I need a system with a beam that she would interrupt when she sits up.  Thanks again for the input.  I will go find this playground thing.............LEE

Hello, my name is Larry E Elliott,  My wife is confined to bed and  is not allowed to sit-up for long periods.  I would like to build an alarm to sound  when she does.  This not a life and death thing, it would just be convenient to know when she first sits up so I can go she what she wants.  I have an Aduino board and can build simple stuff.  Could you please recommend a system that I might build to help me with this project.  Attached is a Sketchup of her room.

Thanks for what ever help you can offer, Larry  615 969 0688

Thanks James, I ordered one today.

Thanks James, I looked everywhere on this.  I am on my way to buy a book on processing.  Do I also need a book on C?  If so do you have a recommendation?

I thank you for the concise answer,  LEE
10  Forum 2005-2010 (read only) / Troubleshooting / Re: Converting  MAC address on: November 29, 2010, 09:12:08 am
My Arduino ethernet shield has a MAC address like this (90-A2-DA-00-27-C8)
The script wants it like below.

Is there a converter for this?
 
// assign a MAC address for the ethernet controller.
// fill in your address here:
byte mac[] = {
  0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED};      
// assign an IP address for the controller:
byte ip[] = {
  192,169,1,20 };
byte gateway[] = {
  192,168,1,1};      
byte subnet[] = {
  255, 255, 255, 0 };

Thanks James,  the info.  How do you stop a program thats running on the board?
 
The script I was using was from the examples tab "Pachube sensor client".  These files where  at the top "#include <SPI.h>
#include <Ethernet.h>" should there be more?

Also, is there a listing of the error messages in the IDE?  I looked before the post, but no luck.

I found this note at the top of the listing:  Circuit:

 * Analog sensor attached to analog in 0     (This I get!)

 * Ethernet shield attached to pins 10, 11, 12, 13  (This I don't get)  The thing Just plugs in on top of the other board. Does it not?

Thank you for the help, LEE

HELP!! What does this mean?  "IP was not declared in this scope "  And what do I do about it?

Next:  Is there a test script for this device?

Another question.  What does the stop button in the IDE do?  If I have a script running.  I can't make it stop by clicking. Am I missing something here?    

Thanks, LEE

How do you determine the IDE version?  At the top of the IDE I have it says "Arduino 0021" is that the right place to find it.  

Also, I have after much searching found only old stuff on the net, some of it is two years old.  I am very confused about what to use.  The stuff on the Pachube site seems to be out of date also.  That is probably why your posting has been hit 1100 times.

I am not trying to make this work for fun.  My start-up company builds super new clean classrooms.  And I am trying to prove to Mr. Money-bags, that internet based technology is the way to go.  And that this Arduino-Pachube thing is the future.

I bought all new boards, both Arduino 368 and Ethernet.  Now on to workable firmware, I hope.

Help Please,  Larry
