Thanks. I've made some progress. See https://github.com/jmoenig/Snap--Build-Your-Own-Blocks/issues/1830

I am now wondering if using the [http://snap4arduino.org/#http](Snap4Arduino local server) might enable one to run NetsBlox in one tab and Snap4Arduino in another. A student could then program NetsBlox to send data to Snap4Arduino using the HTTP block or the like. (Packaged up in a friendly user-defined block.) Snap4Arduino could receive the data as a message and as values of variables. NetsBlox could even ask for values of Snap4Arduino variables to know what data to send.

I tried to test the feasibility of this but ran into a problem right away. I tried localhost:42001/broadcast=MESSAGE, 127.0.0.1:42001/broadcast=MESSAGE, and 163.1.225.137:42001/broadcast=MESSAGE but couldn't get anything to work (I just got "localhost didn’t send any data.")

After posting this I will send a link to this thread to the Snap4Arduino discussion.

Thanks for the response.

Your plans are interesting and promising. While I personally am OK with simulated sensors I expect that will reduce the appeal for many students and teachers relative to real hardware. But I see your point about feasibility and cost.

This won't help in my project but see my next post.

In our project we would like students to combine the NetsBlox services (and other web services) with physical computing on a Raspberry Pi and/or Arduino. The ideal system would have blocks from both extensions of Snap!. Note that we are happy to use the Chromium extension to Snap4Arduino so it is completely browser-based just as NetsBlox is. For the Raspberry Pi we can run NetsBlox unaltered by adding blocks that communicate with a local web server that talks to the hardware pins. Is my guess right that combining NetsBlox and Snap4Arduino is a large undertaking?

Thanks. That is good news. Is there a way to access this database or is the idea that we should be running our own server?

For a research project we would like to perform learning analytics on a log of user's actions. Given that actions/events can be sent to a collaborator could those events instead be saved?
