如何在 Android 和 Arduino mega2560 之间建立连接

Question

I have an Arduino mega2560 which has a WiFi connection. I want to add a button to the Arduino so whenever someone clicks on it (physically), it sends a notification to my Android app (which I am building now).

I have tried to look for a way to do it and I understand now that I need to build a server. I have zero knowledge with servers. How can I start with this? am I in the right way? do I really need a server? where can I start?

As you are probably using a serial module you can just use the arduino wifi library. Here is how to make a wifi webserver https://www.arduino.cc/en/Tutorial/WiFiWebServer ... for the button you just have to use a typical digitalread of the input pin.
