How to send lightroom data to arduino?

has done this?

 

i'm industrial design student working on project in school , want 2 way communication lightroom. want have physical output (led's, turning knobs) sits on desk next computer. send commands arduino not problem, i've done want output

has advice begin, or me out?

i can program in arduino pretty good, , have basics in python

 

 

thanks!

(if haven't already, download lr 5 sdk, includes complete documentation.)

 

there few documented mechanisms lr plugins send data external programs:

 

- lrhttp module lets plugins invoke urls or post commands.  external program implement local http server receive gets , posts lr plugin.

 

- lr plugin write log file, external program poll continuously changes.  while might offend more delicate architectural sensibilities, little tuning can make pretty responsive without costing in cpu.

 

- plugin invoke external program via lrtasks.  if external program reasonably lightweight, can perhaps several times second without consuming excessive cpu.

 

for receiving data lr plugin external program:

 

- plugin can establish urlhandler receive http requests "lightroom://" urls made local programs on computer.

 

- plugin can poll external program using lrhttp using , post commands.  external program responds when has data send, cpu overhead low.

 

- plugin poll log file written external program.  haven't tried direction, might harder tune such polling in direction, given limited capabilities of lr sdk.
