Arduino Class

On hold again

Well, my plans just don't seem to be working out.  I've had some more health issues, first with the recovery from my last surgery, then early this week I fell again but this time I hurt my good knee.

Once I am recovered enough I'll be scheduling the next class, I don't want to jinx myself and set a time because it seems like whenever I do something else happens.

Next Class

Well, I got busy with some issues at work, and haven't been able to work on the communications or the wind anemometer.  I'm going to try and get some time on it next week, but I'm going to go ahead and schedule the next class.

We'll have our next class on March 18th, and I'll add it to the calendar.  We'll work on the communication between the station and the PI, and also the Anemometers.

Last Class

We had a great class, aside from the people who were out sick, but we worked on the communication from the weather station to the inside console.  I had some problems getting the radios to work in the weather station software and I'm working on getting that fixed now.  We did go through doing the Raspberry PI initial install (and finally got Van's display working) and discussed the anemometer.

I'll be redesigning the one we decided on to make it a little more weather friendly, and then I'll be printing them for the next class.  The other parts I all have except for the hall sensors which are about $6 a piece, and I'll order a bunch and everyone that wants one can pay me at the next class.

I'm hoping to have the fixed software for the NRF24 radios integrated into the weather station code and working by the end of next week and then I'll publish it on the github repository.  Those of you who are familiar with GIT and would like to contribute to the code just request access and I'll grant it for you.

I'll also schedule the next class next week, and right now I am shooting for the first or second Saturday in March.

Class Saturday

Well we are all set for our class for Saturday.

In working on getting the Raspberry PI working with the NRF2401 I ran into some issues, so instead of connecting directly to the weather station like I originally planned instead we'll use the second Arduino that we were going to originally use with the LCD as a bridge to the Raspberry PI.  The Arduino inside will have the NRF2401 module and will talk with the weather station which I've already proven out, and then it will talk over serial to the Raspberry PI.   We will need logic level shifters to convert the 5v on the Arduino to the 3v GPIO pins on the Raspberry PI and I have 15 of them we can use.

I've also found a nice case we can print for the Raspberry PI, and then we can start designing the case for the external weather station, and I also have picked out an Anemometer that we can print and build for our weather station.  I haven't found a tipping rain gauge I like yet, so I'll keep searching or we may have to design one ourselves.

We will meet at 9 am at my work, 635 Vine Street in Winston Salem, and if anyone arrives late just give me a call at 336-289-9262 and I'll come up or send someone to let you in.  Again you can park in front of the building, there should be enough spaces there, and we'll order pizza again from Burke street if everyone is good with that, or as an alternative we can order subway which is right up on 4th street if someone is willing to run out and pick it up.

Rough itinerary for Saturday:

  • Test the NRF24 on our Arduinos and make sure they are all working
  • Setup everyones Raspberry PI
  • Setup the second Arduino that will talk to our weather station, and we'll set up unique ID's for everyone so we can all test at the same time.
  • Setup the Arduino to Raspberry PI connection.
  • Discuss the next steps for the cases, anemometer and rain gauge.

Looking forward to seeing everyone Saturday!!!

First release of the weather station code

The first version of the newly refactored code we'll be working with next weekend has been updated on Github.  

This is the new format we'll be coding in, and it includes the code for the temperature sensor.  

I'll be working on the code for the other modules that will build on this and posting it to Github as I complete them.

I also have a surprise for everyone for the class next weekend, but you have to be there to receive it :)

Parts List Updated

I just updated the parts list with the new UV sensor and all the links have been verified to work.  I also added a link to a Raspberry PI kit that is sold on amazon that is very nice.  It comes with the SD card pre-loaded with NOOBS (the operating system for Raspberry PI) power supply, video cable, a nice little case, basically everything you need to get started in one place.

In addition to that parts list you'll need the general supplies like breadboard wires, breadboard and cable for your Arduino, monitor, keyboard and mouse for the raspberry pi.

By no means feel that you have to get that one, and you can get any raspberry pi board at it will work with our project.

Looking forward to seeing everyone at the class next month.


Upcoming refresher class

Ok, I've had at least one person respond so that's enough for me to have the refresher class.  Right now I'm shooting to have it on 9/3, but I need to make the arrangements with my work and as soon as I confirm it I'll post the update here and announce it.

Our headquarters is right next to Wake Forest Biotech Place, and is very convenient to both I-40 and 52, along with the restaurants in downtown Winston.

As soon as everything is arranged I'll announce it.


Class update

The next class has been scheduled for October 1st at the Red Cross. We will be working on the weather station with the refactored code and the new light sensor which I will have for everyone. I'll be reposting the updated parts list and the code before the end of the month so everyone can be ready for the class.  

I know that the Shelby Hamfest is on the third of September, but I wanted to see if there was any interest in a refresher class for people who ar eavailable or are starting new. We would go over the basic Arduino environment, and help people get their laptops all setup in preparation for the October 1st class. If you are interested in doing this please email me asap. If we have enough interest I'll announce it here in the next week or so. If we do have that class I'm also planning on holding it at my work as its been graciously offered to provide space for the class.
