• Error in the code?
  You must be logged in to reply.
  
  
  I built this project this weekend. Worked ok in the end, but I noticed that there was a disconnect between the schematic/fritzing diagram and the code.
  
  The code calls for the pushbutton to be attached to pin 12 of the Arduino... but the schematic doesn't show this.
  
  Didn't matter to me much as I was making modifications anyway to remove the computer serial monitor stuff, but if someone were to follow this code/schematic verbatim, I think they would have issues.
  
  The basic concept works great, though. I've got rev 1.0 on the counter right now incubating my first batch. Rev 1.5 will have a serial LCD attached, once I figure out how to integrate it properly.
  
  I'm not a huge yogurt fan, but I am a foodie, and always enjoy understanding a process. I hope to apply what I learn here to an upcoming project - a blower motor for a smoker BBQ - this summer.
  
  Anyway, thought I'd point out the error in what was otherwise a fun and interesting project.
  
  Thanks!

• Wire for probe?

  I'm looking at specs for wire, and seeing most has a temperature limit at 90C, when I can find a specification. This concerns me with making this project, as the 185F = 85C only 5 degrees from the limit of the wire. The point the wire contacts the cooker would be hotter, possibly quite a bit hotter. It looks like you used a long piece of heat shrink over it, but that might not be enough.
  I'm just wondering if there's a particular wire source that's good to use in this kind of application that I'm not finding. I already have obtained the rest of the parts and put together the relay board. All I need to build the sensor probe and wire things together and I can test it.
