I am getting this module to send and receive text messages using a uno clone.

I just set it up with this schematic

I have pin A3(17) for the off and on portion just using the pin in place of the switch No resistor.

Big thing I found to get it to work was setting the serial on the module to 9600, so the clone got all of the message prior to that it would only get a little bit of the incoming text.

I have been asked several times for the code for this control.  Thought this might be the best place for it.
The story is my wife bought a used manual kiln.  They are a pain in the butt to baby sit while fusing glass. I am a cheap skate and did not want to spend the $150 $200 bucks for a pre-made one. At that time I had just found the Arduino platform. I purchased one as well as the buttons and LCD from Sparkfun did some reading and found this shield  then got to work.

It took me a couple of weeks to figure it all out. A few missteps and very hot kiln for the first trial run, but got it pretty well ironed out.

It uses a Potter & Brumfield Relay 92P7D52-12 run by a TIP102 soldered into the shield. I don't have a schematic just kind of did it as I went along.
I think I left enough comments to follow and help someone understand what is going on.
Don't be to harsh first Arduino code still learning.

I live in a region where the socialist government tries their best to foist ill-fitting Euro solutions

Your tag shows you as in the USA - where's the socialist government?
Awol, from his central Oregon reference earlier, I have a feeling I know where he lives roughly speaking.
I would believe round abouts annoy him as much as others I know.
That particular cities goverment is fairly liberal.

Anger is a good thing to have as you do evil genius stuff, for revenge.  smiley-twist

Very nice work by the way

Have not to this point played with analogue in and I am not a electronics guy,
but the equation sensorValue = sensorValue * 0.00488; should give a float type value.

Wonder what is going on.

Here is where I got mine for a kiln control I did recently, He also has a library for the arduino.

and I was able to get the major voltage i.e. 1 ,2 ,3, 4, just need to figure out how to get the minor of it, .25 etc, so a total voltage reading of 3.25 as a example.

Another total noob here but I would think changing sensorValue to a float instead of a int would get you what you want.

I do have the highest +karma though - maybe people are just feeling sorry for me smiley-grin
I went through a bunch of your posts yesterday, too understand why your negative karma was going up.  

I didn't see an obvious reason so I did add a positive. Could be a previous life thing. smiley-grin

Yes, +1 to you smiley

Thanks so +1 to you as well. smiley-lol

SparkFun came to my rescue, Here is what I used for my LCD.  It only uses one pin for serial but it is more expensive than just a plain LCD.

The library I used

As far as my inspiration was the the HABS project and reading stuff in the PID loop post by Brett, zer0vector, and you.

I have been asked for the code several times and have sent PM's to people with it was wondering if I should just post it here, but really does not seem like the correct place.

Pwillard thanks for the kudos.
The little misses was interested in getting it done NOW so not much choice on tinkering.  

I wanted to change the case that is cracked but was warned on threat of death that I will not take it apart.

Once again thank you

I will I am not a great code writer.  Probably better ways of doing then what I did.

Where be the appropriate place to put the code?

I never wrote a parts list or made a schematic.
 The SSR that I used is a Potter & BrumField T92P7D52-12 which is what was recommended by the company I got the original control mentioned in my first post.

Reasonably price at Digikey.

I did finished it up on Sunday.  My wife loves it
I am not a EE or anything so dont have a schematics.
I used the MAX6675 from here with his library.  I was able to wire in my switches and a transistor to run the SSR using that shield.
In the code I ended up using the PID beta6 library. The code follows the system96 glass fusing specs and does a decent job of doing it.
The final fused glass products look good.

Hi all  smiley
I know this is an older post but was wondering if any one had started a kiln controller. Could use some pointers or a start.

I am new to Arduino(first post), I plan to use it to control a stepper motor.

But got to thinking that it would also work perfect to control a kiln.

Would be a honey do for the misses we are looking for a older small kiln.  She is getting into fusing glass and currently she is using a 27" kiln that I had converted to a programmable control. I bought the control for that conversion and don't want to spend that kind of money again if I don't have to.

Besides gives me a reason to play in something new to me.

I have the thermo coupler and bought a maxim6675 from McLaughlin Engineering as well as some spare SSRs from the previous conversion.
Found the PID Loops library and have been doing tons of reading in this forum the two weeks.

My background is in manufacturing engineering but spend most of my time now writing Gcode or VB code that creates Gcode.  I built my own 4'x8' router table(purchase electronics) and do some PLC programming when I have to as well.  I have not written in C in a long time but I am sure it will come back.
