I need the communities help. I am currently working on an engineering project that will require my team to access and control the Arduino from a webpage that can be accessed from any computer (Not just a computer on the same network). The goal is to take the computer out of the picture from the project, so that the device could send and read variables from a custom website. The device would use a WiFi card connected to a home network. Does this exist? Is there a tutorial that I could use to be able to develop a custom website that can send and receive data from the Arduino through a WiFi shield that does not require it to be connected to the computer?
I know there are several websites that offer reading of pins but I would like to be able to pass variables. I am totally down for using a website if it provides the ability to pass variables and not just pin control.
Because of intellectual property rights I can not post the code or the design. I am just looking for someone to be able to point me in the right direction to get me started.
