Anybody interested in custom libraries/programs for Arduino?
I've been playing around with the Arduino CPP-like language for a while now, and have really been enjoying it. I was wondering if anybody was
interested in having custom libraries/programs written for them. I've written a few libraries so far, and the most recent few have turned out
extremely well, but I've run out of shields and displays to write code for. If anybody has something they'd like coded or ideas for programs to keep
me entertained, I'd be greatly appreciative.

I'd be especially interested in experience (and notable successes or failures) you or others have had using an arduino as part of chemical experiments
or processes.
I have had fantasies of using one to measure and control temperature, pH, and current in a (per)chlorate cell, or measure temperature of a still-head
etc etc - but have never got around to actually implementing anything.
If you are just looking for an idea - write something to log the temperature taken from one or more strategic points on a distillation rig to a CSV
file during an entire distillation.

I use one to control stiring on a little servo motor.. XD a ver very lame use of one but it works for the most part.
I just made you read this very pointless signature. How does it feel?

If you will search a year or two ago there were a couple long threads on this subject with a fair amount of discussion on the topic of using Atmel,
Picaxe, Arduino, and Raspberry Pi for various monitoring and controlling in chemical experiments.

Should I write it for a 10k SS thermometer? I've never used a pH meter in anything but a lab, and I don't own any of my own. As for the temp control,
I could write the code for a mosfet H-bridge driving a peltier cell and have it heat or cool based on the temperature read by the thermometer whenever
the temperatures fell outside a pre-determined range. Adding code for an IIC or UART driven 2x16 or 4x20 Hitachi-based LCD wouldn't be a problem. For
the logging I could have it save on a second, minute, or hour basis to a .txt file using an Arduino Uno SD card shield. I don't know anything about
the architecture of a CSV file, but I'll research it, and if it seems do-able I'd add it. I've never really done much combining Arduino and chemistry,
although separately I've done plenty of each that it's not hard to imagine the possibilities that come with combining the two. Forgive me if this
takes me a little while, I'm 17, still in High School and finals are coming up in a week so I might get to it around the 16th.

So here's what I got so far:
Spent about 5 hours on it today, I mostly just set up the temperature reading and conversion and figured out an error report and debug system. ~300
line of code so far, with comments it's about 400 lines.
| Code: |
/*Arduino Temperature Data Logging Program,
Wittten by Andrew Spangler (andymadman),
KG7BHQ for you hams out there, I would recommend the Seeed Studio SD Card Shield
V3.X (any V3 will work) for the SD card interface, although you can probably change
the code to work with other SD shields/devices. For the LCD, any I2C,(IIC so no one
will be pedantic about it) backpack will work, and for the LCD try and get a hitachi driver
20x4 character LCD as thery have more than double the usuable printing space and displaying
data is a lot easier than it is on a 16x2. I've written this program to work with both 16x2
and 20x4 LCD displays.

EDIT:
It looks really bad here so I'm going to save it into a CPP file and put it up for download so it can be viewed on
the Tutorials Point Online IDE or on your favorite CPP editor. (I'm using a cpp editor rather than the Arduino IDE because my sister is hogging
the Mac and I'm stuck on a Chromebook without access to JRE. They have the same format so it doesn't change much other that the ability to compile.)
EDIT:
I'm hosting it on my blog so I can manage versions of the code.
http://theexperimenterlife.blogspot.com/
Look on the top right where there is a widget that says "Downloads"
It's the top right one that says "Temperature Datalogger (V0-0) 1-9-15"
For the record, all of my non-libraries will be managed by version followed by date,
so this is Version 0.0 and Date 1/19/15.

Wow - good work !
You've shamed me - I will have to get a usable temperature probe(s) happening myself.
Have you used your program in anger yet ? If so - what are you using for your temperature probe ?
I've ordered this glass adapter from deschem - but still have to decide what to use for the actual probe.
Earlier you mentioned a "10k SS thermometer" - is this the sort of thing you are talking about ? - the price is right - do you have any experience with using something like this with an
arduino ?
[Off Topic] Your quote code looks OK here - but you know you _can_ kind of use the arduino IDE / eclipse / whatever from your chromebook by tunneling
X sessions from the mac :- this guy talks about how he did it.

Thank you! 
That is the kind of thermometer I was originally thinking of, but I realized that something like this would probably work better as they sell them for much, much cheaper on amazon, comparable ones are usually a dollar for a 25 pack. If you
think it's a good idea, I could put something in the code to allow either kind of temperature sensor by having a Boolean in the human-controlled
variables. I'm just worried that I'm going to exceed the maximum program size if I put too much in. I've done that a few times now and it's always a
bummer having to spend hours shaving off bytes to get everything to fit onto the Arduino.
In regards to the temperature probe itself, I have used them before and they work quite well. They're usually accurate to around +-5 degrees at
high-ish temperatures and +-1 degree around room temp. Usually I have them heat-pasted to a motor driver on a robot to prevent them from overheating.
Sadly I can't tunnel to use the Arduino IDE as my sister is usually actively using the Mac on her profile and because of the way it's set up, I
couldn't access my sketches as she doesn't have read/write privileges to my directory.

Ah - the TMP36 - I think maybe the first sensor I ever used with an arduino ! They are good - but kind of limited - best around room temperature - not
so good past 100C. I also found them kind of big once you start thinking about putting them in a glass or plastic tube. (I'd really like something I
could use as a drop-in replacement for a traditional glass thermometer, and also something that can take several hundred degrees)
I briefly messed with trying to monitor the temperature of an electrolytic cell - at one point I was planning to wire a TMP36 up, then dip it in epoxy
to protect it. (The environment in the cell was crazy corrosive - I did try stainless steel tubing, shrinky tubes, and hot glue - all with predictably
poor results). If I were to revisit that project, I would prolly try heat sealing one of those 4k probes in a flint glass tube.
For now I am waiting on my 24/29 glass thermometer adapter and 4k probes from ebay.
btw - you _can_ run graphical X-windows apps tunneled over ssh from the mac using your account, while your sister is locally logged in with her
account - its not windows - your mac has a proper multi-user OS under the hood. (BSD Unix no less). The only real conflict would be if she were to
shutdown, or take it off the local network while you were using it.

If you ask me, PICs and Picaxe are the best, but that's just because I prefer Z80s, and those are the best modern derivatives, though they're
technically slightly different.

I use PICs a lot; they're less powerful than Arduinos, but also a lot cheaper and simpler.

Okay. I've used a couple of TMP36-alikes with a Spark Core in the past to monitor and control the temperature of electrolysis of magnesium sulfate to
make copper sulfate, and then have it upload and log the results on a secondly basis to a server. It worked pretty well, but I've never had to use
them at temperatures over 100C so I am unaware of how they work at higher temperatures. I usually just completely covered it in ceramic inside the
tube of a cheap plastic pen. I did try sealing one in a boro-glass tube, but the high temperature killed it.
In regards to the Mac, my sister is usually editing videos or similar tasks and running the two processors at 90%+ each, so there's very little
processing power left for other programs to run. I've only used Ubuntu in the past and had problems windowing X11 over a proxy. I'll look into it, but
my guess is with my lack of admin/fakeroot privileges I'm not going to be able to run the root-privilege processes required.
Thanks though for the information, it is greatly appreciated!

I wouldn't say that, unless you're revering to the picaxe, not PICs (by Microchip).

No.
Well - it would if you had a quantum noise sensor.
Does atomic decay count ?
'cause look what I found on the internet. (how cool is the internet ?)

..so I dont know if the random numbers would actually be random - but they'd certainly be cool - so I'd sign my certificates with them any day !

really is easy to get TRN from quantum noise. I contacted with elektor usa but no reply.
this use exclusive code, in C? ASM? basic?
