Yay, I did it (baby steps)

funinalaska

Ok, I managed to get my DS18B20

and my outdoor thermistor

to display on my LCD

all being driven from an Arduino Nano clone.

I know this is probably a minimal feat for most people out there, but for me this was a big thing.

Now, at least this part is good to go when I get my ethernet shield and other hardware I am waiting for the next phase of this project.

The only thing I need to do yet is calibrate the thermistor.

 

If anyone wants to pick on my coding, I am attaching my pathetic code here.

 

I appreciate input, but please be nice.

 

Right now the actual device is very ugly because the LCD is on one breadboard, the Arduino Nano is on another and the thermistor is hooked up to yet a third.

I am also waiting for a big breadboard to arrive, once it gets here I will clean it up and put up a picture of my mess.

 

My wife just keeps laughing at me.

  • Thanks DAB.

    I just discovered a question I have.

    In the long run this project will be a multi function weather display.

    I totally forgot about one thing I ordered.

    I got a real time clock module for the project but after thinking about it, the final project will be connect to the network/Internet to get airport METAR data.

    The question is, would I be better off to just use the network for time or to use the RTC module?

    What takes less code as I am sure by the time iam done with this I will be pushing the memory limits.

    Also which option will be easier to integrate?

    I assume (possibly wrong) that once you power on an arduino and It gets the time from the net it can keep it till it is turned off. Is that correct? So I will only have to have it get the time once, or is that what you need theRTC module for? To maintain the time?

  • Hi Andrew,

     

    The first project is always the toughest.  Everything is new, you do not fully understand everything you read and you lack the confidence to believe in yourself.  Everyone goes throught that phase.

     

    I have never completed a project in which I did not look back and see a dozen things I could have done better.  Unfortunately, nearly all of my work projects were technical demonstration projects.  We only had to prove that technology supported the idea.  The prototype helped to isolate those areas where further technology development was needed.

     

    I for one, never make fun as new people learn.  You really have no idea about how much you can do yet.  Do not be afraid to fail.  If you are not failing, then you are not challenging yourself enough.  Failing teaches you ten times more than a quick success.

     

    Engineering and making is a process and a journey.  You get better with practice.

     

    So keep on trying.  Even the Wright Brothers learned to crash long before they learned to fly.
