Great video, thanks for putting this out. When I upload the sketch I get a connection refused from the Arduino Ethernet Board R3. I'm using the Windows install of Mosquitto, from what I can tell the connection is acctually being refused. I can see the traffic in a PCAP capture. Any thoughts would be appreciated.

It works! Now I have a doubt. How can I connect multiple topics? to control 2 or 3 leds.

Great video, quick question. I've tried installing mosquito on the raspberry pi (stretch) having a lot of difficulty. Ant help would be great

Hi, have you ever used Arduino Yun? I have to use ethernet with my arduino, I want to choose between Arduino Yun and Arduino Ethernet, I wonder if you have any experience on the Yun. Thanks.

Thanks for the great video. I keep getting this error

exit status 1
stray '\357' in program

When I search this error people say it happens when cutting and pasting code from a website, which is exactly what I am doing. can you upload the sketch somewhere.
I really appreciate your work on this, it is a huge help.

Thank you! I was working on it and having problems.. but I discover after a while that my problem was the password... without pass I can do it. That's because the password is encrypted and I was writing it normal on arduino code. any way, now its fine.
