Is it possible to have a program on my mac read plain text from a web page and send to the arduino through a serial port? I know how to send the data, but how could I get it?
Probably one of the easier ways would be to use wget; I am sure there is a version available for OSX. Then you would use (command line) "wget " (basic use) which would download the page to the current directory, and from there you could do whatever you needed to with it...
Thanks!
