Does anyone work with arduino or similar?
Hi, playing around with an arduino project that I want to do, and I'm running into problems with it. Something similar to http://www.instructables.com/id/TfCD-Cl ... ermometer/.
First step I'm working on is just reading the temperature. I got a basic Uno R3 with a starter kit. Trying to use the thermistor in it.

Is the lesson from the kit. Also includes the code I'm using.

Is how it's wired. It seems to be getting the correct temperature give or take four or so degrees off my house thermostat, but applying heat decreases the temperature it's reading as. So I'm not sure if I have it set up for the wrong thermistor type(IE the kit thinks it provided one type and it provided the other type) or there is an issue with my wiring or something.
I think if I can get the temp right, the rest of the project is basic programming with the led ring, which is pretty straight forward. And then of course producing a case and what not, but whatever on that front.
So if anyone knows anything that could help that'd be great. I'm thinking I might try just getting a different temperature sensor.-

Huh. Now that I look at the website that is what they are showing. Which is weird because https://learn.adafruit.com/thermistor/u ... thermistor has the power going to the resistor.
And by following that I got it working. Having power going to the thermistor produces numbers WAY WAY off.-

Well, they seem very similar in terms of using the exact same numbers and although one does everything on one equation and the other one breaks it up they seem the same but I don't really care to break down the make and figure it out I guess. I'm sure that's the difference in there some how.
Anyways, I'm just excited to get it to work consistantly. Now it's just settling down for a temp range for the sensor, from cold to hot and then the hard part in making a case for it.-

So far it doesn't seem to be too far off. More then likely I'm just going to stick with a thermistor as I need to run it out a window or so for an outside temp.
I'm mostly glad that I got the rest of the project up and running in terms of using the temp to control a Neopixel Ring, as a gauge for the temp, but that was all pretty basic coding and a bit of math. So not really too hard.-

Well, I got my thermistor with a long wire a while ago, just now ordered and recieved some prototype board so I can solder the circuit into place and attach it to the bit I had made with my library's 3D printer. So I'll actually have a project shield all set up. Pretty exciting stuff. Sometime in the next few weeks i'm going to break a bunch of things with soldering.-
