Introduction
This post is a custom creation with arduino which allow us to connect the car to our smartphone with wifi.
One of the thing which is neccesary to improve is that the arduino provides a wifi (ad-hoc) and the phone connects to it, this way disables the internet from the phone, because is connected to a wifi which don’t provide internet access.
Build
First of all I used this “Arduino” called “NodeMCU – ESP8266” which can be connected to a wifi or generate it.
A part of getting the necessary hardware, we need to know the wiring diagrams of our car, to be able to control it. For example, I checked the door relay to be able to open/close the car remotely.
The next step is to configure the NodeMCU, to serve a web page on the port 80, to access its ip and view it. You can find multiple examples on internet.
In my case, I used two arduinos, one will read and action in the engine bay, and the other one will serve the web and also will be connected to a screen showing information.
