A minetest Mod to control a real Arduino YUN with the REST protocol
With the digilines_arduino block you can send REST POST command to a real Arduino connected in the same WLAN. You need to set the channel to connect the block to digilines and the IP Address of Arduino.
With the LUACONTROLLER function:
digiline_send("ch1","digital/13/1")
you will send through the channel ch1, to your YUN, the POST :
http://192.168.1.44/arduino/digital/13/1
You need to install on your system the lua-socket library.
Tested only on Debian 8. May be buggy. Comments and suggestions are welcome.
