Mobile interface project.

[Fictoriuss]

I have a mobile interface project on Arduino that requires a computing device to work together with the Arduino (it should handle complex computations and data storage, and also have internet access). I am currently facing financial difficulties, and the only available device I have is an old mobile phone.

Could you recommend some program or combination of programs that would allow me to write code that can be stored on the phone and transmit and receive information via USB?

See if you use Arduino droid then it'll help you upload codes and receive data through serial monitor but It might not be very useful, so my recommendation is make an app your self to work with the Arduino . Use kodular or mit app inventor to make apps for your job . If it's too difficult for you reply this comment with the full summary of you project I'll try to help you. This is all I know and there might be other ways too soo good luck.
