 ====== Ethernet xAP Arduino Library ======
-To aid writing xAP compliant applications for the Arduino an xAP processing library has been written.  This allows Arduino to be connected to your LAN and will transmit xAP messages without any HAH involvement. See http://wiki.london.hackspace.org.uk/view/Project:Ethernet_Arduino

 These are the classes exposed by the library.  Grab the source and browse to see the inner working.

 Step 3. Now we will create a Lua [[hah_plugboard_v2|plugboard]] applet and a BSC endpoint so this LED can be easily controlled.  This will take care of converting the xAPBSC.cmd message into a xap-serial message for us, along with providing xAPBSC.query capabilities, and regular xAPBSC.info reporting about the status of our LED.
-Like all Plugboard scripts, this must be placed in the /etc/plugboard directory on the HAH. The vi editor is included in the HAH Busybox operating system build, so you can create/edit the script directly from a Telnet session onto the HAH. Remember that your script filename must end in 'Applet.lua' (case sensitive).

Also check that you have enabled the plugboard scripting engine and the serial schema services via the HAH web UI (Automation/Assists tab).

 Step 4. Restart the plugboard daemon to make sure the new Applet is loaded. One easy way to do this is to reboot the HAH.
-Step 5. Send a BSC control message to our endpoint and turn the LED on/off. An easy way to send BSC control messages is to use xFx Viewer.
