I really love embedded world and more exactly Arduino and I did all sort of projects but I have difficulties on doing something with a Mobile Application & Arduino.
I want to do a project for a friend which involves showing if a pushbutton was pressed or not on a mobile app (Android).
The workflow is like that:
I have an Arduino which is connected to the a local wi-fi and the phone which is connected to the same wi-fi network. The user will start the app from the phone and it will see the state of the button in real time without doing something else. If it is pressed the screen should be green if it is not pressed the screen should be red.
Of course, later on I will do more complicated stuff such as reading sensors but in the beginning, I want something simple.
What I know for sure until now:
• How to wire and get the state of the button of Arduino.
• I think I need a running server on Arduino.
My skills are: Embedded C, C++ bit of Python and a bit of Java. I think for this project I need php like, skills.
Can you tell me from where to start? How should I do, and what parts do I need? Any links will be appreciated. I tried to search on the internet but now I am more confused. I get answers like LoLin, ESP, Php but not a solution.
Thank you for your support and I am waiting for your responses.
