I liked your web site very much ...
There are various ways in which I can see it being used to teach control applications ...
e.g. by connecting the server back end to a raspberryPi ... and running various Lua scripts
directly on the RaspberryPi ....
If you look at the RaspberryPi workshops I have announced here ... you will note that there
is no Lua workshop currently scheduled (www.absolutebeginners.uk.com
However, if you look at the FTT web site which is running more extended courses you will see that
there are Lua courses for the RaspberryPi.
It occurred to me that you might be interested in running a workshop describing what you have done ...
Also of interest, to me, anyway, would be a description of how you designed and built your web site
so that other teachers might be able to emulate your work ... or even setting up a wider community.
You may also be interested in BRON ... they have a code generator for generating finite state machine code ... and have a free 8 node version that can be used on the RaspberryPi.
