Question for those of you that are really experienced w/ Arduino.
I just bought an UNO about 4-5 weeks ago, and have been teaching myself the code and the circuitry. The last time I wrote code, it was in Clipper for dBase III+ (read: a long time ago).
Ive got the thing reading a DS18B20 successfully, running PID, and writing to an LCD the way I want. Ive got it running on breadboards now, controlling a crock pot. My code is crude and mostly plagiarized, but is working exactly like I want it to. Im cooking a lamb sous vide right here on my desk.... pretty cool. Im asking it for 135.00F and its giving me 135.05F. So, its time to come off of the breadboard an onto something permanent.
The original plan was to install the UNO in my control box, and make a shield (practicing w/ the PWM project I have in other threads). Then I found the Arduino nano on ebay for $12, and decided to use that. I was going to make a board, and install the nano on it like a chip. Then...
Finally, I just finally got it what they mean by prototyping platform. Dont laugh, but I just figured out that the intent is to get the project working, then rip the 328 off of the UNO, install it into a 28 pin socket on my own board, and then use the UNO over & over & over again with a fresh 328 each time.
I notice that Yuri went the shield route.
Further, I dont see too many projects where people have just removed the 328 and used that... so the question is: Why not? I have to make a board regardless of the decision. A new 328 w/ the UNO bootloader is <$5, and it would seem MUCH easier to integrate a DIP28 onto my own board rather than adapt the Arduino (UNO or Nano, either one) to it. What is it that Im not realizing?
