Open a program using an RFID-reader

Projects Interfacing w/ Software on the Computer

Hello all,

how can I open a program on a computer using RFID?
I have a few different tags, depending on the tags a program needs to open. I succeeded to read the tags and convert the information to a certain value, but now I do not know how to open a file outside arduino. Is there a command to do this?

Preferably, I need to open a GUI using flash, but I guess it will take the same command.

Thanks in advance!

It depends on what OS you are running but you need a program on it to take the input from an arduino and do the actual opening. You can write this in any language you want. On a Mac apple talk is great for this.

I am running OS X 10.7

How can I make that program in Apple Talk?
I am not that experienced in programming...

Isn't there a command that just opens a filepath?

Yes but you have to get something listen to the serial port and then translate that to the path name, there is nothing that just reads the serial port and then issues it as a command, think of the security implications of that!

You need SerialPort X to handle the port input in apple script from

I am not that experienced in programming.

So now is the time to learn.

Hers is a simple apple script application to read the serial port and then do something with what you get:-

set arduinoPort to "/dev/cu.usbmodem1d11"
-- this opens the port and resets the arduino
set arduino to serialport open arduinoPort bps rate 9600 data bits 8 parity 0 stop bits 1 handshake 0
if arduino is equal to -1 then
	display dialog " could not open port "
else
	repeat -- repeat forever
		-- wait until something is sent
		set bytesIn to 0
		repeat until bytesIn is not equal to 0
			set bytesIn to serialport bytes available arduino
		end repeat
		set cmd to serialport read arduino for 1
		set cmds to cmd as string
		-- display dialog "Command recieved = " & cmds
		
		if cmds is equal to "1" then
			display dialog "Command 1 recieved"
		end if
		if cmds is equal to "2" then
			display dialog "Command to quit recieved"
			exit repeat
		end if
		
		
	end repeat -- of the forever repeat
	-- note this next bit will reset the arduino
	serialport close arduino
end if

You need to change the first line:-
set arduinoPort to "/dev/cu.usbmodem1d11"
to match what you see as the arduino on the serial port.
