I'm new at this (just got this today) so please bear with me...
I'm trying to figure out how to send an HTML command to the R.P. to run a command. I can play a sound file by running this command...
sudo aplay alarm.wav
...but I'm trying to figure out how to do this remotely. I would like to setup a schedule to send this command to the raspberry pi at a set time but need to figure out how to do this with an html command.
