I tried to install ArduinoDroid from google store. I get a message that the app is not available for android 14.
Any tips on how to go about it ?
I see that the most recent release of the app was apparently over 3.5 years ago:
The ArduinoDroid repository was last updated 7 years ago.
You may have to roll your own. One option is to use App Inventor.
If you are comfortable with Python, you can build an Android app using flet. I have a GitHub project that controls an Arduino UNO R4 WiFI over TCP/IP.
I was able to create the app, test it on my PC, and then build an Android APK that runs on my tablet.
Here is the code to give you an idea of what is involved.

Big thanks. I will buy a pc 
Use an .apk from Uptodown.
What version?
The latest version on Uptodown , Android 11( presume it works on Android 14 as well).
I see a new version is now out:
So if you are still interested in this App and haven't already found a solution for installing it, it would be worth another try.
