How to make Android and Arduino communicate without a wireless module

I developed an Arduino application in which I can control LED 13 through a serial monitor.

I.e

  • if I find 0 on the serial monitor LED on pin 13, and
  • If I type 1 in a serial monitor, the LED turns off.

Now I want to do all this with my Android phone. I have the following questions:

  • First of all, how to create a PHP server to get all this.
  • How to open a local host on my Android device so that it works as a local server
  • How to make the server communicate with the serial port

I do not ask for all the code and the project, but just show me the way, and everything will be fine with me.

Most Android and Arduino devices cannot talk to each other when they are right out of the box — no changes to the hardware and / or system software are required.

You have a choice:

0) Bluetooth is pretty clean and is now in the $ 20 range, so it’s one of the most cost-effective solutions and one of the least likely risk factors for damage to the phone’s hardware. But you said you did not want this.
