Arduino USB without module

Using Arduino Project Guidance

Hello everyone,

I wondered if I would have been able to read files stored on a pen drive, attached to an home-made USB module (simply the female port with the 4 pin attached to arduino in some way).
Thanks,

Lorenzo

to read files on a USB drive you need USB Host capability, e.g.

Thanks a lot

Hello again. I was planning to buy this module. Before buying it, however I want to be sure that i will be able to read and write files on a pendrive attached to it and, in case, with which library?

Thanks again

Lorenzo

WHat does a 'pen drive' mean to you?

Is this a USB flash drive of sorta?

Where is the link to the product?

Where is a link to the schematic?

The product you linked to mention Android as well? (why?)

Check out Circuits @ Home, and their USB Host shield....(but also the libraries and some background on usage)

Yes, sorry I meant flash drive. the link to the module I wanted to buy is

https://www.amazon.it/Modulo-Scheda-Espansione-Android-Arduino/dp/B01KL4IO98/ref=sr_1_1?ie=UTF8&qid=1516127938&sr=8-1&keywords=usb+host+arduino

But I don't know why he mention Android... I had chosen it because was cheap.

Anyway, I think it would be better if I explain the problem as you can try to help me.
I need to read and write files on a flash drive with arduino. I discovered that I'll need to use a module. Once I've bought this one

https://store.arduino.cc/usa/arduino-usb-host-shield

or another, I will have to program it. Is there a library to read and write files on a flash drive through an usb module?

Hi,
What is the application that needs the Arduino to read/write to a memory stick?
If you want to store the file on the Arduino, how big is it and in what format?

Thanks.. Tom.. :slight_smile:

horace:
have a look at
SD - Arduino Reference

The sd library is good also for a usb flash drive attached to an usb host shield?

I don't want to store files on the arduino. I want arduino to write a file to the usb flash drive attached to it (through the usb host module)

Hi,
Did you google arduino writing to usb stick

What kind of files? Text files?
