I have an Arduino mega and GSM shield with the code set on it, I have a mobile application that send SMS to the controller to turn the devices on and off, once the device status get updated, the controller updated an external MySQL DB. (till now it all works)
What I need is to add wifi/ethernet sheild so it get orders from either sms or via router or local network.
Will share the pin layout and all other information once we make a deal ;-)
