Arduino Class
Sorry for the late notice, but I was just scheduled for a production deployment Friday night and Saturday morning, so I won't be in any shape to do the class. Not to mention that I've had a sinus infection for three weeks and haven't had a chance to prepare properly.
I'll set another date for April when I get a breather next week.
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.
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:
Looking forward to seeing everyone Saturday!!!
Had a slow time, but it was good getting the radios working for almost everyone. I'll work on having a better testing program for January's class.
We will take a break during December for the holidays and then pick up on January 21st with working on setting up the Raspberry PI weather station console, designing the case to hold the weather station, and get started on the anemometer, weather vane and tipping rain gauge.
I'll have an updated parts list for the new parts we'll start on in January, and I'll have extra parts that people can buy at the class.
Thanks again for everyone who came to the class!
I've updated the parts list on Amazon with notes about how many are needed for the weather station and which parts are optional and why.
Ok, I've confirmed that we'll be having the class here at my work Inmar on Saturday the 12th of November. Thanks again to David Mounts for allowing us to hold the class here.
The address is 635 Vine St, Winston Salem, NC.
I've also created a list on Amazon with the parts we need for the class, it'll be easier to update than the spreadsheet. I've posted the link on the links page. Of course feel free to get the parts from other vendors like Banggood, Sparkfun, Adafruit, it's totally up to you where you get the parts. If you're not sure if the part is the same one go ahead and email me a link and I can double check it for you before you order it.
Thanks!
Had a great time on Saturday, and I hope everyone else did as well. We went through and made sure everyone understood the new code and got all the way up to the point of working with the RF radios.
During the next class what we will do is go ahead and connect the radios up to the Arduino's, and test them and how they communicate with another Arduino. I'll have a master Arduino with a display that will poll the weather station for weather data and display it (which was the original design). Anyone who wants to build this part is welcome to, it's going to consist of an Arduino with the NRF module, the Nokia 5110 display and a couple of push buttons. I have a LOT of push buttons if anyone needs them, and I think I'm going to work on mounting a couple of sets on breadboards so they can be plugged into the Arduino easily.
Once we have everyone's Arduino communicating properly, then we'll switch over and get the Raspberry PI's setup and configured. If you have an extra monitor please bring it, otherwise you definitely should bring at least the Raspberry PI, a keyboard, a mouse, whatever SD card is needed for the version of Raspberry PI you have, and a power supply. We did find some nifty small 7" LCD screens on Amazon for about $30 and that is a very convenient option especially for the class. If not I'll have at least one monitor possibly two that we can use to get everyone's Raspberry PI setup on the network and we can use them through VNC on your laptop.
We will then go through the basics of the Raspberry PI and how to connect things to them, we'll probably hook up a light and some switches and program those. Then we'll go ahead and hook up the radios to the Raspberry PI and try and get them talking to the weather stations.
I'm going to be working on the software for the Raspberry PI this month, and also on building an anemometer and a weather vane, which should be very easy to hook up.
Right now I'm planning to have the next class on the 12th, and I'll post again once I've confirmed that I can get the conference room here at Inmar.
Thanks!
