Internet of Things workshop

  • May 31, 2015 · 10:00 AM

How about a workshop on using your arduino to build your own internet of things? You can turn any simple sensor or actuator into a fully networked smart device. Whether you want to make a remote controlled crock-pot, rfid door lock, or full scale home automation system, MQTT is a convenient way to to do machine-to-machine M2M communication. I could also show people how to monitor/control their devices over the web (apache/php/node.js/io.socket/etc)

W

e could setup a MQTT broker (Mine is running on my Rpi)

People could ma

ke sensors:

- pushbuttons

- rfid readers 
- photodiodes
- etc

and Actuators
- lights
- relays
- servo-motors
- crock pots
- etc

And we could get them all talking to each other over the MQTT network.
(You just need an Arduino + ethernet shield to participate)

Is this something people would be interested in?

    Next is to program an arduino to publish and subscribe to your Rpi broker:

    Get the Arduino MQTT Client:
    http://knolleary.net/arduino-client-for-mqtt/

    The Arduino client comes with some example sketches in File > Examples > PubSubClient

    Here's a link to my example which controls an LED:

    I'll do a more through writeup but this will get you started:

    Install MQTT on your Raspberry Pi with these instructions: http://jpmens.net/2013/09/01/installing-mosquitto-on-a-raspberry-pi/

    I recommend stopping after the "sudo apt-get-install mosquitto ..." step, unless you actually need certificate based security.

    Is this event going to happen today, or has it been rescheduled?

      Hi Brett, It was nice meeting you today. Even though the event did not happen, we did end up having nice productive conversation/

    • Sarvesh V.

      Will send you an email later.

    Great to see you making this happen Dilip! I was the one who originally posted the suggestion for the meetup, and never heard back until I saw the email reminder for tomorrow. Dilip or Russ, do you want any help running the event? I would be happy to bring my hardware and/or share all my code?

    May 30, 2015

    • Sarvesh V.

      Please send me the links and code snippets and that have you if possible.

    • Sarvesh V.

      Thanks again for your MQTT insight !

  • Brett R.

    To answer my own question below - no, it did not happen. But a few of stood outside and had a good conversation.

  • Dilip

    Guys, I have contacted some teachers who can conduct a workshop, but didn't get reply yet. Will keep you posted. Thanks

  • Russ

    I am not hosting this event, I am unsure who is running it.

  • Dilip

    Anyone interested in the workshop in June 1st week?

    I think I am going to delete this pending event, as it has been over a year and I am not sure who posted this.

    I would love to go to an android workshop at "You-do-it". Since it was over 10 months ago that this was posted, it looks like we need new organizers. Is there still interest from everyone?

    December 5, 2014

  • Matty

    How about a date set? A sunday afternoon would be nice! We could eat lunch before we begin. I'd say May 25TH or June 1ST, what do you think?

    kids today are coding and programming by the time they enter middle school. This is a good meetup for both adults as well as kids like my son! We are in!

    I love it! A learning environment and DYI, something I can finally convince my son to join me in. I remember the days when my son was very young tinkering with electronics, taking them apart and then when I tell him oh yeah now try to put it all back together, he would amaze me he had the memorization of where all the tiny microchips go and if a piece was broken he would create one from scratch melding wires and all. Kids are natural innovators and creators. I want to get him involved in things like this before he loses the desire to tinker. There is nothing like this in my area so I will join this group with my son.

    Ditto, very interested. New to this kind of dev and looking forward to learning a lot.

  • "You-do-it" Electronics C.

    We may be interested in hosting your workshop. Please contact [masked] with more info

    I've been reading the MQTT spec and would love to see it in action.

  • Keith

    I'm VERY interested in this. I have experimented with setting up a home environment monitoring system, but getting sensor nodes to talk to a base station is surprisingly challenging.

  • Harvey Y.

    I'm in too...LMK the date/time if it happens

    June 10, 2013

  • Matthew M.

    I would show :-)
