Stuff trickles in and challenges continue

funinalaska

So I got more things in the mail today that I will eventually need to utilize.

I received:

Ethernet shield

More LEDs (gonna make a cube eventually when I need a change of pace and have time)

a DHT22 sensor

 

I am still waiting for a decent amount of things to arrive, but and also significantly behind on learning how to use things.

I am struggling with learning how to utilize 7 segment displays using multiplexing, but I am sure eventually I will figure that out.

I am beginning to look at the final idea I have for my weather center project and am beginning to worry about my power supply. i think I may need to get a larger 5V regulated supply than what the arduino produced when I add in 3 different displays including LED matrix and 3 digit 7 segment and LCD with backlight. I am planning to use an arduino mega for the final project, but still unsure if it will be sufficient.

 

I am beginning to realize that this is a VERY ambitious project for a beginner, I hope I don't get discouraged.

I am hoping that when I am done with this project that I will be happy with the results and that it will be used for a long time.

The big issue up here is the extremes of temperature.

I would like to find a better temperature sensor to use outside that has a little lower tolerance for cold temperatures. Our normal low temps are pushing the bottom of most of the affordable digital sensors I have looked at and that I can get libraries for the arduino for.

    Ya it is exciting,

    and yes, I am already getting to that point of where do I start, but I figure that learning each component individually is a good place to begin.

    Speaking of I am still having issues with 7 segment displays, But I am short on time this week so hopefully next week I will have more time to try to figure this one out.

    Then next I need to learn the ethernet shield, I am sure that will take me a month.

    I hope my second UNO gets here soon so I can stop completely disassembling one project before starting another.

  • Hi Andrew,

     

    Yea that early phase while to toys arrive is always exciting.

    After a while, you look at all of the boxes and say "Where do I start?"

    Just follow the engineering process, take it step by step and have fun.  The excitement is just beginning.
