	''' Load the sample Arduino code into your Arduino board - ''' Here is the code I used. I will not claim it to be pretty, but it does work as a test for this method. Most likely you will have to modify some of the numbers around the input. I will give you my schematic, but I am sure that your set up will vary somewhat and that will change the Threshold and Voltage reading numbers.

	''' Load the sample BASH scripting text into an executable file in your shared folder from Step 4 on the Linux box - ''' Here is the BASH script. It is a script that goes into an infinite loop and constantly polls for two files, a ''command'' file and a ''clear_log'' file. When it sees those files it takes action to either send commands or clear the log file. The files are sent from some other application that are used to control the communication to the Arduino. In this example I use AutoIT as the controlling software (See Step 9). I will leave it to the reader to decode these commands.

There is a drop down menu with four commands that that will make the Arduino respond. This program will create a ''command'' file, fill it with the command string and place it in the Network Dir. The Software will wait 5 seconds and then retrieve the results and place it in the text window. Then the program will place the ''clear_log'' file in the Network Dir. I will not cover the use of this software here, refer to the User Guide section. For now just get this loaded into AutoIT and hit F5 to get it to run. You can run AutoIT programs interpreted or compiled. Pressing F5 runs it as interpreted.

	Open an explorer window or a command line window and go navigate to your mapped drive and path. Check the directory and make sure there is no ''command'' or ''clear_log'' files. Then start up the Arduino_Com_v.01 script and send a command. Now check that mapped directory and make sure the files ''command'' and ''clear_log'' are in the proper shared directory. If the Arduino_Com_v.01 script just shuts off, then it could not get to the Network Dir that you provided. If you provided the correct Network Dir and it still crashes then try to re-map the drive again. If the program does not shut down, and you do not see the files in the directory, then you probably have a valid location, but it is not the correct directory where the ''CommandPoll'' script is runs.
