I am now have difficulty solving a critical part of my graduate project.
I am asked to develop a UI that can transmit a string of characters to the server of wifi(operation invisible to the users). Moreover,it is required to refresh the data whenever I pressed the on/off button.Otherwise, Arduino won't receive any valid signals from users. What kinds of tools can I use to develop for my project? If you have any solution or idea of the problem. Please leave a message below, I am appreciated.
