I am trying to use the following setup as explained in the link to link my arduino which resides on my tracked bot.http://www.ebay.com.au/itm/Uart-WiFi-Module-Starter-Package-Kits-Arduino-Compatible-/270941705511?pt=BI_Robotics&hash=item3f15625527
As explained in the description on ebay and in the manuals (using the test setup), I have gone right up to the point where the wifi module is independently working as a server and when i go to my browser I get "Hello world" message from the wifi module.
Now the problem: This setup essentially is as follows: The arduino uses the serial.println("Hello World") command to send a line to the serial bus as a string "Hello World". The wifi intermediate shield converts the serial message to TCP format and is read by the main wifi module. Then the wifi module transmits the webpage via wifi connection which it established through your home wifi network.
Now, I need to know how to do the reverse using VB.Net
My program running on a PC/Desktop will need to send motor drive commands (essentially in the format: 0 or 1, 0 to 255) to the arduino via the wifi connection. The PC will also be linked to the same wifi network.
I am completely clueless at this moment as to what needs to be done. To begin with I would love to be just be able to send a simple 0 or 1 to the correct arduino pin and turn a LED on or off.
Any ideas on this? Anyone has used this particular wifi shield? I have seen many people using XBee shield and Synclab shield using wifi.h library. But nothing like that exists for this shield.
Any help is super appreciated.....
